Okay. Converted my .avi file to a mpeg2 or whatever, for DVDs. And I used the TMPGEnc DVD Author to burn it on a DVD disk. It works fine, except that the video gradually lags behind the audio as the movie goes on. So, it doesn\'t look like it\'s lagging at all at first, but at the end of the movie, it\'s WAAAYY off.

I split the audio to a .wav using Avi2Wav.  Then I did all that in TMPGEnc.

So does anyone know what to do?

Hi,
playback the mpg file that TMPEGEnc creates and see if it has a problem. You have to do this to see if the problem is created by TMPEGEnc or TMPEGEnc DVD Author.

It was TMPGEnc.  I also tried to convert it to a VCD .mpg but it did the same damn thing.

Got any ideas?

If you have an NTSC video and you are trying to create a PAL then sound problems are very common.
Try changing this option.

I selected NTSC, so I don\'t guess that\'s the problem.  But the frames/sec is 23.976 and I selected 29 per second for the mpg DVD thing.

But when I tried to convert it to a regular mpg for a VCD I had the same problem, even when I selected 23.976 fps, so I dunno, I guess it\'s just a bad .avi?

The problem with NTSC DVDs is that I have very few to try and find varius problems. Your problem seems to be that, so I suggest you follow the way I show in the VCD To DVD guide. Demux the audio from the video usinf VirtualDubMod. Then encode the audio the way I show in the guide (changing the frame rate to 29,976 using the setting just under the MPA decoder option). Then encode only the video using TMPEGEnc (make sure you select video only) and then author the DVD and see if it works.

Could you link me to that audio tutorial? I can\'t find it.

Edit:  And will I have to make them into VCD first? Because the audio is off when they are VCD\'s too.  Feel free to IM me on AIM.

There is not tutorial. I meant the VCD tutorial. Just to demux the file (split the audio from the video) open the file in VirtualDubMod and go Streams -> Stream List, select the stream and click Demux. This should save an mp3 or other file that you are going to load in BeSweet and edit the way the VCD guide shows.
Then encode the file to MPEG2 the way the TMPEG guide shows and author both audio and video files.

Please AIM me next time you are online, because I am having some trouble with Virtual Dub Mod.  Hell, I am having trouble with everything.
