Hi,

selected from another dvd karaoke,the problem is I am missing one track
of audio(can not take out the voice to play karaoke).
Please i need help for build a dvd karaoke.
Thank you very much

what are the steps you use to compile your selection of songs? it seems that the second audio track is dropped along the way. Use TMPGenc/Mpeg Tools/De-multiplex to check your mpeg after each step to make sure the 2nd audio track is still there.

If I read it right your problem is that you have an audio track in AC3 I assume, but you don't know how to get rid of the vocals on that track.

One way I have read how to do (have not tried it myself) is to first convert the 2 channel AC3->WAV then open it in something like Audacity (which is freeware) or Soundforge (which is not) and subtract one channel from the other. As normally the vocals are distributed equally across both channels the vocals will cancel itself out.

For me, i think Ulead sofware can't do this job.
