i got the plugin so i could hear the ac3 sound from my vob files in the playback window as i was editing. it has worked with everything until i got to the special features of my dvd. there are these sets of interviews in twos, and the second of each set will not open in the program. the error message tells me these files have no sound, although they play fine in my dvd player. they will not open because the project will not support "different" audio formats, and "no sound" is effectively different from ac3. i have been able to open them as a separate project, however, they indeed have no sound (within the program). nobody at the tmpgenc site seems to have a clue! please help if you can, it must be something too obvious.
