How to remove the Vocal from Karaoke video

[dduong]

Hi,

I have some Karaoke songs in Vob and want to remove the vocal from it. I burned them to DVD-R but The problem is that the vocal is still on when I try to play it with DVD player. I just want to keep the
video with lyric only. Please help me how to do it.

Thanks,
DD

I guess it's burned in the video and then it's not so simple. You could crop it or use some blur filter but it wont look that fine.
