I haven't used handbrake in a very long time. We are about to go on a road trip so i thought i'd make a copy of several movies we own to entertain the kiddos... and tried making a copy but the result was all garbled video. I downloaded the newest version (1.0.7), and now it won't even make it all the way through the encode (and its so much slower than it was back in the day). Is there anything i'm not getting...?
