Hmm, that's odd. So you ran them through TMPGEnc to make them into DVD-compliant MPEG2 files, yet get sync issues when playing the movies on your standalone DVD player?
First, you should try creating the DVD-compliant files as individual streams. If you're using any of the more powerful DVD creation programs, they'll prefer the individual streams, and in most cases insist upon it (some will demux a combined file its self). Now that I'm at it, was DVDlab one of the programs you tried? That should not cause any errors its self, and unlike any other DVD creation program I've seen (and I've seen plenty), it will inform you of any possible errors at every step of the process. It will tell you if the video and/or audio is not DVD compliant. If you used this program and didn't get these errors (and followed all the other file conversion steps we talked about), I'm not quite sure what the problem is.
If you used DVDlab and got some of the errors that the program tells you are non-critical, made the DVD anyway, and then saw problems, I'd suggest trying to correct those errors. If you used another program, I suggest trying DVDlab
Then try burning the result to DVD using Nero.
A couple pointers:
1) when TMPGEnc converts a file to MPEG2, I've noticed it doesn't actually make the audio DVD compliant (which I found strange). So, if your audio is originally 41KHz, you're going to need to convert it to 48KHz. You can do this in an audio editor like Cool Edit Pro (Edit>Convert Sample Type, choose 48KHz, stereo, etc), or follow a guide like
this one to create and AC3 audio track. The Cool Edit Pro method results in a WAV file (I haven't checked if it can save an AC3 file, it might be worth checking out), but DVDlab won't have a problem with this.
2) Another issue comes when burning the DVD its self. You didn't mention how you were burning yours before. If you're using Nero, the trick is that when you're choosing the type of disk to burn, choose:
DVD > UDF (
not ISO) > Version 1.02 (for compliance with the widest range of standalone DVD players
That's all I can think of at the moment. I've been doing some cool stuff in DVDlab recently. At the moment I'm making a great concert DVD with a friend for an
awesome band
