Choppy picture and sound on DVD playback of movies

[pellets]

Hello

I was not sure on which part of the forum to post this, so i took a chance at this one. Anyways..here goes:

I have the last half year encountered a strange problem i would like to tell you about.
Sometimes, when trying to watch movies i have burned onto empty dvd-r media, i encounter severe choppy picture and sound only a few minutes after having started the movie in my stationary dvdplayer.

It doesnt happen all the time, but once in a while.
And its very annoying when it first happens.
And, whatever i do, i dont manage to fix the problem.

It happens on 5 out of 10 movies I burn, so its annoying enough.

When burning images like *.iso, *.img, "video_Ts" etc of movies i have always used either dvd decrypter or Nero ( newest versions ) of the program.

Before starting a burning-session i always:

disable my antivirus software.
close all other applications.
I use a type of media which i have not had any problem with before.
The two programs i tested with was Dvd Decrypter ( latest version) and Nero Burning Rom ( latest version ).

What annoyes me is that on half the movies i burn there is no problem, but on the other half this problem occurs. And i use the same programs and media on the movies that works as on the movies that doesnt work.

Anyone got any tip on what the problem is ? Please let me know.

Best regards

could be a media problem as media suppliers do change ..

could you tell us how you made these dvd's ? i.e. what bitrate, settings , authoring program , etc ?

because if you are just burning what someone else did - you might just be burning crap ...

A year ago i brought with me 10-20 movies to a friend of mine. ( Movies i had bought in the local store ) He is situated in the other part of the country. We sat down and watched thiese movies for a week.
When i left back home, i forgot to bring with me these movies.
We therefore decided that he should make iso, img- etc images and let me download them from his server. ( Legal backups of my own dvds as you see). So, that other people makes this images doesnt mean its crap, especially when half of it works.
I dont recall now what kind of program he used to make the images though.

I forgot to say that i encounter the same problem when i watch the movies on my pc, so its not my dvd-player that its the problem i think.

I also think i have the same codecs etc now, that i have always had.
Its really become an annoying problem to me.

Another thing...I usually use the same media "Dysan DVD-R".
And i have burned both movies that work, and movies that doesnt work on the same type of media. I therefore looked away from that being the problem.

[BJ_M]

for sure sounds like a media problem ..

Dysan media is real crap ...

[pellets]

Hehe
Well, I have used other dvd-r media also.
But, unfortunately i dont recall if i had the same problems back then.
Anyways...once in a while Dysan works also
As mentioned in the earlier post.

But, i will test other mediatypes now this upcoming week.
Do you recommend a special type of media for burning backup of dvds ?
And can you tell me why that spesific media is better than e.g Dysan?

Do you use labels on the DVD's? That might be causing problems.

Hello

No, I have never used labels on the dvd-r, neither before nor after burning.

Hello again.

Heres what i tried since last time:

I installed Daemon Tools, and mounted the movie-image. ( an iso-file)
I then choosed to watch the movie with Power DVD. I now had no problems watching the movie. The watching went smooth on my pc.
I therefore concluded that the iso-file itself couldnt be the problem.

Then...

I ran a "Dvd Lens Cleaner"-disc on both the dvd-player on my pc, and on my stationarry dvd-player.

After that i did the following:
I closed all apps i had running. ( Word, explorer etc...)
I disabled my antivirusprogram
I opened Windows Task Manager and choose the "processes"-tab. There i closed all unnecessesary processes which were running.

I inserted an empty dvd-r media of the TDK-branch into my dvdburner on the pc.
(Previously i had been trying Dysan, which i have been told lately is crap. Therefore i went to TDK which is know to be a

good brand, in the same category as Verbatim ).

I started the burningprocess by doubleclicking the MDS-file following the *.iso file. Then dvd-decrypter opened ( latest version )
In the burning-options i chose to burn at half the speed. I have a 4x dvd-burner ( Plextor), but i chose to burn at 2x-speed.

After finishing burning im exited ofcourse.
But no !
The film still has got choppy sound and picture. Wtf ? I now get very depressed, heh

I go into the sound options of the movie. It has got the alternative to choose between Dolby Digital 5.1 ( standard) and DTS

5.1
I ensure that the sound is Dolby Digital and i try both with english subtitles and with no subtitles at all. The problem still occurs.

So, I have still the same annoying problem. Anyone got any other tips ? I would surely appreciate it.
As mentioned earlier this happens on 50 % of all the movies i burn, even if i use the same media all the time.
Untill today i always used Dysan Dvd-R.
But even with TDK, the problems occured again.

Anyone got any more tips? Please give me a reply to this post. Im starting to get neurotic

if the dvd was made with to high a bit rate - it will play fine on a pc , but will crap out on a standalone ...

whoever made the dvd doesnt sound like they knew what they were doing ..

now that youy have given some more info --


remove the DTS track and see if that clears it up ..

you will have to reauthor it ..

if not (check elem. m2v file with bitrate viewer - should not go over 8000) you will have to re-encode the dvd to a lower bit rate .... use the source dvd for best results ..

[BJ_M]

and tdk also has good and bad disks .. brand name means nothing

[pellets]

Hello

Thanx for the reply.

I would really like to try removing the DTS track.
Is there a spesific program you recommend that i use for this task?
Can you explain it to me roughly how i do it? Im a fast learner, so if you just could explain it to me roughly i should be on the way...

What exactly is the elem.m2v file?

I dont have the source dvd, since it unfortunately has been destroyed in an accident. I only have the iso-file. ( and the MDS-file).

For both the two tips you mentioned above..Should i first use isobuster to extract all the files in the 8 gb iso-file, before i start authoring?

Best regards

[pellets]

Hello again.

I have now tried the following:

I used DVD2One to remove the DTS-track.
I then downloaded the bitrate viewer.
When starting this program, and going to the "browse" button, i didnt see any m2v-file in the VIDEO_TS folder, only vob, ifo and bup-files.
Can u educate me a bit more on this please?

Best regards:

[BJ_M]

try it without the dts track .. prob ok ...

the vob files are the ones with the video in them ..

[pellets]

Hello

After removing the DTS-track i burned a copy onto an emty Dysan-dvdr.
When playing the dvd on my pc-dvdplayer the movie playback goes smooth. So, thats an improvement though.

But, when playing the dvd on the stationary dvd-player, the movie actually seems worse. Even more choppy sound and picture.

OMG ?

So, whats left to try, heh...?
Do you have another tip, or could u tell me how to check the bitrate/ change the bitrate if necessesary of the vobfiles? If this has to be done, to test it.

(I didnt burn the disc on the TDK, since using tdk also failed in previous tests. )

Best regards:

[BJ_M]

i would demux the whole thing ...

check the m2v file (elemenary stream) for max bit rate .

re-encode it to a lower bit rate if required ..

reauthor the dvd

burn it with a good burning app to good media ..


or even easier -- go out and buy a new copy of the dvd

[BJ_M]

guides for all these steps are on the left ... many different methods

[BJ_M]

but you say it "It happens on 5 out of 10 movies I burn, so its annoying enough. "

so it sounds still like crappy media and/or burner and/or burning app and/or how you are making the dvds in the first place and/or your system and/or operator error and/or your player


pick any combination of the above ..

[pellets]

But, i cant find the m2v-file anywhere in the video_ts folder.
There are only vobs, ifos etc there.
And i should use the bitrate viewer to check the stream? ( But first i have to locate the m2v-file somewhere though...)
Do i use the bitrateviewer also to change the bitrate?

Appreciate it if you could tell me that.

Best regards:

[BJ_M]

i would demux the whole thing ...

then you will have a ac3 file and a m2v file ..

re-encode it to a lower bit rate if required ..

you will need a mpeg2 encoder to do this .. see guides and tools

reauthor the dvd

you will need to get authoring program to do this - see guides and tools

burn it with a good burning app to good media

you will need a good burning app for this and good media ..

or even easier -- go out and buy a new copy of the dvd

you will need your wallet for this

[pellets]

You have been very helpful so far, and my conciousnes in one way forbid me to nag you further but....im desperat so...here goes:

1) What do you mean by demux ? If there is a program one can use to do this, please let me know the name of it. I wont ask you for help to use it, i only need the name.

2) Could you be so kind giving me the name to an appropriate mpeg2-encoder?

3) Could u be so kind giving me the name of an appropriate aoutorering program ?

I have a good burning program ( nero and dvd-decrypter)

My wallet dont like to buy a new copy

[BJ_M]

dvd-decrypter can be used to demux the streams - use stream mode .

lots of encoders - look in the tool section .. but tmpgenc , mainconcept , canopus basic and CCE basic are very popular - there are also some free ones listed ...

authoring - tmpgenc also has an authoring program, dvdlab is also popular - and many more are listed in tools - a few are free , most are not ...

most of these tools together you need would cost maybe $200 and up . a new dvd is far cheaper - but there is freeware also listed -- but in some cases , you might have to do more work .. and learn more to do it going that route ..

[pellets]

Hello again

THanx for the useful info.
I will look into these programs during this week.

Best regards:

[pellets]

Hmm..Hello once again...

Now i used dvd decrypter.
I chose the Mode-IFO setting.
Thenafter I chose to, in the stream processing tab, to "enable" streamprocessing for all of the choices mentioned in that tab. Both for video, audio and subtitle.
Then I started the streaming.
But, after having finished, and checking the output-folder.
I cant find any ac3-file, or any soundfile for that matter, anywhere there.

i end up with the following:
1 exemplar of Stream Information.txt
1 ex VTS_06_0.IFO
1 ex VTS_06_1.VOB
1 ex VTS_06_2 - 0xE0 - Video - MPEG-2 - 720x480 (NTSC) - 16~9 - Letterboxed.M2V

1ex VTS_06_3 - 0xE0 - Video - MPEG-2 - 720x480 (NTSC) - 16~9 - Letterboxed.M2V
VTS_06_4 - 0xE0 - Video - MPEG-2 - 720x480 (NTSC) - 16~9 - Letterboxed.M2V

But, no ac3-file.
When inside the Dvd Encrypter program i surely see that there is a m2v and a ac3-file, but after finished processing i cant find the ac3-file, but instead the files mentioned above.

There is a file there called Streamer information.txt, and this file says the following:
"
0x20 - Subtitle - [SubPicture 01: Wide/Letterbox] / LBA: 20459 / PTS: 00:01:12.338 / Delay: 72105ms
0x21 - Subtitle - [SubPicture 02: Wide/Letterbox] / LBA: 20458 / PTS: 00:01:12.338 / Delay: 72105ms
0x80 - Audio - AC3 / 6ch / 48kHz / DRC / English / LBA: 6 / PTS: 00:00:00.233 / Delay: 0ms
0x89 - Audio - DTS / 6ch / 48kHz / DRC / English / LBA: 5 / PTS: 00:00:00.233 / Delay: 0ms
0xE0 - Video - MPEG-2 / 720x480 (NTSC) / 16:9 / Letterboxed / LBA: 1 / PTS: 00:00:00.233 / Delay: 0ms
"
At least, there is the soundfile menitoned.....
Anyways..thats one problem.

I install ( after having bought) tmpgenc. There it occures the framrate is 8500 kb per sec.
You said it shouldnt be ove 8000 kb / sec for television? So, i assume the problem lies here?
Anyways..I cant find any option in tmpgenc for me to reduce the framerate at all. Is there another program you could recommend for me to accomplish this task?

Will surely appreciate any help.

Best regards:

[BJ_M]

you have to select the audio stream to get it , make sure it is checked also ..


you can change bit rates in tmpgenc to anything you want ..... don't know what to tell you-- just set them ... there is a ton of guides here on how to use tmpgenc .

use VBR

use a bit rate calculator to determine the correct values - but dont go over 8000 at max ...

[pellets]

Hello

Thanx for reply.
I indeed checked the audiostreems also.
I even repeated the process two times, just in case i hade forgot it the first time, but no..same result.

Since i the first time used dvd decrypter to read from the dvd-r, in the dvdplayer, and got a read error; I decided to use daemon tool to mount the iso-image, before i opened the iso-file inside dvd-decrypter.
I now got no read-errors, but whats similar for both approches is that the audio-file didnt get extracted for some strange reason.
Even though i checked that it was checked....

Urk

[pellets]

Hello once more.

I really would like you to visit the following url, where i have posted a screenshot of what i did in dvd decrypter.
Everything looks ok?

Hello again

FOr some reason i cant find where in Tmpgenc i should be able to set the bitrate for the movie myself. Quite annoying, urk...

But, yesterday i found a program called Rejig.
When i use the Dvd Backup function of the program ( after previously having mounted the movie iso-image in dameon tools) a lot of processes started; both fluxing, defluxing, correction of audio layer etc....until a new set of video_ts and audio_ts folders had been made.
When i burned THESE onto an empty dvd-r ( Dysan) the problem was gone....HEH ?
When playing the dvd-r on my standalone i encountered no problems, and the movie went smooth. Of course this made me very happy.
But, afterwards i started to wonder...

Does this program automatically, when making new sets of videfiles, decrease the bitrate to 8000 or less ?
Or was i just lucky this one time ?
What do you think ? I didnt punch in the wanted bitrate annywhere in the program, i just hit the "Dvd backup"-button and sat down in my chair.

To good to be true ?

Would appreciate any comment.
