Erm. Not a trick question.
I burnt several DVDs with DVD X Copy 18.104.22.168, and all DVDs I burnt was on Maxell DVD-Rs and just about all of them has ONE or more occurence of getting stuck while watching, and jumps to a later point in the movie... When I rewind, the stuff is THERE.
The skip part, from what I know, is like a jump point to go to a later part of the movie. Can't figure out why this is the case. Maybe its a software issue? Or a drive issue?
