Standalone recorders very often output AC3 audio which has missing frames or is not exactly synched with video after demuxing. ProjectX is excellent application but it doesn't corrects AC3 errors.

I used TMPGEnc DVD Author 1.6 to overcome these issues - author or just mux again to DVD and then demux in ProjectX. Also VideoReDo is very good, if not better. Unfortunately both programs are not free.
