DVDx Audio/Video out of sync

[snap]

when using DVDx to rip the movie off the DVD, i get an error sayin "sample not found or audio decoding eror, this is sometimes found at the beginning and end of movies, would you like to fill the audio buffer with blank"

then when i watch the final ripped MPEG the A/V is out of sync until later in the movie, where it has somehow became in sync again...

what is happening?

and also, i have ripped several succesful copies of anime movies.

and can someone please tell me what to put all my settings on? (and no jokes about my computer speed please)
