WinTV PVR-250 stream for DVD

[Anonymous65]

I'll start a new thread about the PVR-250 since the other one is getting so long.

VCD and SVCD seems to be OK when remuxed in Tmpgenc, but Tmpgenc will complain about buffer underruns on mpeg-2 records. However, I have not seen any problems with my SVCD records.

But, I'm getting problems with making DVD-R's. The mpeg-2 file will play fine on the PC, but after the file has been burned to a DVD-R and playing it in the DVD player, the audio gets out of sync. The last DVD-R I burned was a 2 hour mpeg file, and I have some audio dropouts when playing the disk. I'm not sure if the audio gets out of sync because my DVD player can't play the disk correctly, or the mpeg stream is bad, or the file was messed up in DVD Moviefactory when it was making a VOB file for burning?

Does anybody else have some experience with burning DVD-R mpeg-2 files from the PVR-250?

[SHS]

I think it Moviefactory, Even the first PVR dose the same thing, You could test them without burn to DVD disk if I recall rigth dosen't have an option to make VOB to the harddisk? I know UVS6 dose.
Both PowerDVD4 and WinDVD4 have option to play DVD files from a folder or you could use command subst (driveletter): c:\(foldername) up to 8character long max like this "subst z: c:\dvd_temp".

I'm still playing with this issue, and found that the mpeg file needs to be remuxed after it has been trimmed in nanocosmos. So, it looks like every time you trim a cut in nanocosmos, you need to remux the file (which is also the case for SVCD).

Another question:
I have the Apex-660, and with VCD and SVCD's I can hit the Goto button and enter a time, like 60:00:00 and it will jump 1 hour into the disk. This does not work with DVD's. Any other way to jump into the disk other than using the FF button?

sorry skittelsen I don't have a DVD burn at this time have try add scenes which is same thing as chapters

I remuxed the 2 hour mpeg file, and it's still going out of sync. It's starts in sync and goes out a second or two at the end. I'll try other settings in the PVR-250 options menu...

Steve,

I have seen the same audio sync issue a time or 2 with my Apex AD 500W, where a VCD made with my PV-231 is in perfect sync on my HD, but plays out of sync on my Apex. I upgraded the loader in the APEX, and that really helped. Also fixed some other strange problems I was seeing with my Apex, even with commercial DVD's.

Does the DVD play in sync with Power DVD from your computer's DVD drive?

[Anonymous65]

I don't have PowerDVD installed, but there is another DVD player (Windows 2K) that does play DVD's. But, it doesn't do a good job at it.

I tried to cut a file in Tmpgenc, and during the demux of the audio and video streams, the lenght came up to be identical. But when playing the trimmed cut, the audio is out of sync when playing the file on the PC, strange! Also, I'm getting buffer underflow error messages, so that is most likely why the audio goes out of sync with the video.

But, there are many options to select when recording with the PVR-250. On the files with a sync problem I have selected "Program" stream. I will now try to select "DVD" stream, which makes a 10% bigger file, but after remux in Tmpeg is reduced by 10%, and so far, does not give the buffer underflow error messages. I hope the "DVD" stream setting will fix the audio problem on long DVD records.

It's VERY time consuming making 2 hour records, remuxing, and even burning a DVD-R. Also, my Apex will not read DVD-RW's , so I have to make DVD-R coasters! Any help testing long DVD captures with the PVR-250 is WELCOME!

Steve dose the audio get out sync in VCD and SVCD made disk?.

[Anonymous65]

No, I have not noticed any problems with VCD and SVCD. Nor do I have problems playing the 2 hour mpeg file using a software decoder on the PC. It's only after the file has been authored in Ulead it gets out of sync.

I found and installed a patch at Ulead for the DVD Moviefactory. At this point, it seems to have solved the problem. BUT, I must *not* remux the file in Tmpgenc. If I do, the audio will go out of sync even when playing on the PC. Also, you cannot use tmpgenc to trim a file, the audio will be out of sync. The Nanocosmos editor will work, but when playing the file on the PC, it plays back in fast forward without sound. However, Ulead takes the file fine.

It's just amazing how complicated the stream header info is, trimming, remuxing, and authoring mpeg-2 files are, and STILL get the audio correct. You really have to jump through so many hoops to get it right!

So far (and I'm sure there will be changes), this is what you need to do to use the PVR-250 to make the following:

VCD > you should be able to burn directly the captured mpeg-1 file. If Nero complaints, do a simple remux to VCD. Trimming in Nanocosmos is OK.

SVCD > you ALWAYS have to remux to SVCD. The PVR-250 cannot make a SVCD file. Trimming in nanocosmos is OK before remuxing.

DVD > never remux the file before burning. Trimming the file in Nanocosmos is OK, but the file might play strange on the PC (fast forward).

Steve,

Have you tried cutting the SVCD file with Mpeg-VCR? I have read many posts on the forum that seem to indicate the Mpeg-VCR will not only cut the file correctly, but will also make the file compliant in Nero. I also suggest that you update you Apex loader to a newer version if your DVD player seems to play some things odd. I own 2 Apex units, an AD-500W and an AD-600A. Both gave me major trouble with certain disks until I updated the Loaders. You will have to open up your DVD player to see what loader version you have.

Check out these pages for more info:

The top link is for the loader, the bottom one for non loader upgrades.

Ok steve

Barnabas being you own AD-500W I have some one to have made any CD or aka miniDVD with CDR or CDRW disk that work?.
If so what did you use to do this with.
My AD-500W come with firmware version 3 I never had any problem with so far so I see reson to update to firmware version 4

The problem with a mini DVD is that you only get 20 mintes of video or so. I don't notice the video going out of sync until a good 45 minutes into the show. The audio is perfect at the start, but then is progressing more and more out of sync. So, you really need to do at least a 1 hour test to make sure it's OK.

The good news is that the 2 hour test I did is perfectly in sync! Simply DO NOT remux the file for DVD burning, and install the patch for DVD Moviefactory. Strange that the new disk from Hauppauge does not have the latest files (including the patches) for DVD Moviefactory. The original DVD Moviefactory use the same process as Tmpgenc, it extracts the audio and video files and makes them a different lenght. This is bad news for mpeg files that are hardware encoded.

As for editing VCD, just like Nanocosmos, I belive it makes the mpeg-1 file compliant when cutting and saving. Since Nero does not complain about the VCD files, I assume they are fine for long records (another test I need to do).

My Apex has the latest firmware I know of, which also disables the region codes and Macrovision. So, I believe the Apex is working the way it should (and catches bad records).

[SHS]

I know that steve there perfect for age old film cam
Yup Ulead didn't tell Hauppauge anything about it well it to now,
One other problem is Ulead never put a date when they update the stuff.
So have look on there FTP.

SHS,

I gave up trying to make mini DVD's as I never found anything that could author and burn them. I was using an ADS Instant DVD and whatever DVD author program came with it, and as Steve pointed out, the time was so small, it did not seem worth the hassle.

STEVE,

You are confusing the loader with the players firmware. The loader is different and has nothing to do with region codes or Macrovision, but can make a BIG difference on how well disks of certain dyes play back. Give it a try, and you may see that disks that would not play well before play good now.

[SHS]

I just asking Barnabas thank

[Anonymous65]

OK, I was thinking of the firmware for the DVD player, not the drive (loader) firmware...

[SHS]

skittelsen which partch was that you install DMF_SYNC-Patch.exe or DVD_PLUGIN_Patch_E_020606.exe?.

[Anonymous65]

The Sync patch is the one that should fix the audio problem, but I installed them both.

[SHS]

Oh that nice to know.
