I have followed the guidleines for burning a n xvid avi file to DVD... extracting the audio then converting to ac3, compressing the video to a mv2 file with tmpgenc and then burning to DVD the two files with tmpgenc DVD author. The picture quality on the DVD is superb when played in my standalone but there is no sound. I tried opening the video files from the HDD in PowerDVD and they play fine with audio which is kind of weird as when I play the authored DVD with PowerDVD it seems as though it is being played in slow motion with no sound too. I am really stumped at to why I am not getting any sound, anyone have any ideas ?? Thanks in advance.
