With DVDA 5.2, I was able to put a .wav file as the background audio media file for a menu without any problems to and including the burning level. With DVDA 6.0, the .wav file will be accepted when inserted (sounds fine in the preview) however when preparing the DVD the .wav file compresses and does not play when burned to the DVD (or played via the temporary iso file). The rest of the project works but there is silence at the menu level. I experimented a bit by using different wav files as background media with 5.2 and 6.0 with the same preference settings and each time, the earlier version worked while the new one did not. WAV files are supposed to be compliant according to the documentation. It is easy of course to get around it by opening the wav file in vegas and then creating an .ac3 file (which works perfectly in DVDA 6.0) but this extra step shouldn't be necessary.
