Sound Sync problems using videora

I'm having trouble converting Singin In The Rain to ipod format. I rip it using DVD decoder and convert it using Videora. The sound keeps getting out of sync with the video. This didnt happen when i converted Good Will Hunting or Boogie Nights. What can i do to fix this? the disc works fine on any other dvd player.

 

Some programs don't work well for all DVD movies. Just pick other software to have a try.
