hey guys i got a problem here. i have some ktv files (mpeg) that i want to burn to a dvd. these files have dual audio (left is with vocals, right is music only). to do that, i used ConvertXtoDVD to encode the mpeg files to vob and then subsequently burn them. my burning was successful and when i played the dvd i could still hear the left-right separation of the audio. the problem is, my karaoke player cannot switch between the two audio tracks! anyone knows how to do it? the encoded audio in the dvd is AC3 but there's only one stream.
