Almost all the time when i load a dvd (dosent matter if its new or used) using WinDVD or Interactual player, once the movie starts, the voice/lip syncronization is out of line... Does this ever happen to any of you??

My computer is only 1 year old and can definately meet any and usually all requirements for programs/games etc... So whats the problem??

I either have to just keep on ejecting the dvd, and restarting the movie, and or use pause/play repeadedly until its right, but is there a faster way..

This really bugs me in issues of making backups to where i would burn the DvD, and encode it, only to find out that the lip/voice syncronization is out of "whack".

Please help, i will really appreciate it.
