I seem to be having a problem playing back (or even accessing by menue) a DVD (authored in DVD Workshop). When I get to the 45~50 min range it starts to skip and eventually stops. I can go a little longer on my computer than a set top player. Most of my menue starts about the 58 min-on area. The two earlier menue buttons (around the beginning) don't have a problem playing. I was wondering if the size of the mpeg file might have something to do with it?
