I am using TMPGEnc to make a MPEG-2 file of the specific size that I need then using Ulead DVD Moviefactory 2 to take several of these files and burn them onto a DVD. The process works fine - except that when I play the resulting DVD back in either of my set top DVD players there is no audio. However, audio playback is there in either of my PC DVD players.

The input to TMPGEnc are a d2v project file and associated wav file that I got from DVD2AVI working on vob files. I don't understand how the audio can be there from the PC DVD player and not the other. The only way I have found to make the audio work is to replace the audio track in Moviefactory 2 with the original wav file, basically repeating what TMPGEnc did.

Is there something I am missing in the process? Is there a certain format of audio that set top DVD players require that PC ones do not?
