Typical, wont work now

Hi all

Hope someone can help... This is the script..

I created a project and burned it to disk on a spare dvd-rw, just basic stuff without any authoring as I had not yet settled on a authoring program that I was happy with, palyback on standalone and PC, great.

Now that I am happy with DVDLab, I have used Lordsmurfs process of editing a finished DVD which entailed extracting the audio and video back to its original source. Again, no problem, got my two demuxed m2v and wav files back.

Next step was to create some menu's for the project (which is nearly two hours long) which is now finally done.

I use DVDLab to create the the DVD then Nero to burn which I always have done but the problem is now when I play back on PC and Standalone NO AUDIO.... Scrubbed the DVDRW and tried again, Still no audio??.

Well, bugger me, something went wrong so to make sure the audio was ok I imported it into Adobe Premier Pro (but not the M2v) and no problem, the audio is ok.

Any idea's on what could be wrong would be most appriciated as the original dv video is long gone so I cannot start again.

Thanks in anticipation.

Evening,

my guess would be one of the following:

1. The audio is 24/96 PCM which some dvd players (pioneers) have problems with when authored through dvd lab

2. You have a mixture of audio, possibly ac3 dolby digital on an opening trailer or animation and then mpeg audio on the actual video

Try running the dvd through a PC player such as power dvd 5 and switch on the information display then check to see if it shows an audio stream and if so what it is.

Come back to the forum and we'll see if we can fix that disc up for you

Cheers

Thanks for the reply

The finished article on DVD LAb does have a motion menu so I have removed this to see if the audio would be ok, but it must not be that as there is still no audio. I cannot seem to get the audio propeties up on Power DVD (I have version 3).

This is the properties of the audio stream from Adobe.

file 767.42 mb
audio 48000 hz - 16 bit stereo
ave data rate 187.50kb/sec

Still not working, there must be an easy answer to this!!!

Afternoon,

as promised I've taken a look and managed to cause this very problem (by ripping two vobs and then trying to join them), I'm looking at the best solutions now and will post them a little later.

Great, just an update though, I have retried Lordsmurfs process of extracting the m2v and wav file from a finished DVD and now am the proud owner of two m2v files and one wav, the audio plays ok through Premier (but so did the original one) but have not tested to see if it is all ok when added to the m2v files. Problem is, I have imported the m2v files through Womble MPEG Editor and they are ok, but the program I use to join the two m2v files (TMPGenc plus) will not recognise the second m2v as a valid file (reports it is not a mpeg file)so I cannot join them together. Why when the DVD is demuxed does it create two m2v files???. The original DVD was encoded as a single file?

Appreciate your help.

Mike.

Morning,

sorry no post last night was veryyyyyyyyyyy tired after getting in from work late again

Anyhoo I read your post and you say you can import the two new m2v files into mpeg2vcr (womble) but you are joining them in tmpgenc, is there a reson you need to do this ?

MPEG2VCR seems much better and far less glitchy at joining than TMPGENC.

I would load each m2v in womble, then copy to the clipboard then open the second m2v (from the clipboard) and drag the first m2v over onto it to join, then select the whole "joined" clip and record it as a new m2v.

If you used TMPGENC to multiplex the individual waves and m2vs into 2 mpegs you could even end up with a joined mpeg with audio under this scenario.

Will post a little later on the solution to the problem I recreated yesterday, hope this helps

This is getting good.

I only used womble to view the m2v's, did not know womble would join them, learn new things each day. I used DVDDecrypter to extract the m2v files and Vobedit for the audio.

Will have a dabble at joining them with womble later, just got in myself
