Hmm… What program are you using to open the file after ripping it? I’ve had this problem with windows media player AND Quicktime, just the program sucking. I recommend trying VLC just in case that’s the problem. If Handbrake is the problem… I don’t know why it would be doing that. You should check for an update, and then report the error to their website (since it’s freeware, they’ll want to know if there is a problem). You should try out MPEG Streamclip and see if you experience the same problem with it. Handbrake is great for ripping through anti-piracy devices on a disc, but MPEG works fine if your DVD doesn’t have such advanced protection. Good luck! That sucks. If you can’t figure out the problem and you just have to deal with it, I don’t know an easier way than shoving the file into iMovie or a similar video editing program and re-syncing by hand. Which is SUCH A PAIN!
