Unprotected DVD source material. Under language options all available are checked by default and I leave them alone. English, Frech, Spanish, and subtitles. It's Dolby Digital 6.1 AC3. I also use a program called 1<deleted> and this program has no trouble with the audio that VCC has. It's strange to me that after a copy with VCC no program on my computer detects the presence of audio tracks on the copied disk but somehow audio plays on the pc but not in any dvd player I tried. I couldn't even determine what type of audio track was recorded when nothing indicates the presence of audio.
