i get the audio/video synch off when i try and convert vob files with media converter. to fix that, i have to convert my dvd vob files with dvdfab (rip the encryptions off), then convert the vob files to avi with simpledvd, and last convert the avi files with media converter. its a long processs but the audio/video is in synch and the video is awesome

all the programs i use is freeware.
