Does anyone have experience with Magnavox DVD recorders? I am able to play the finalized DVD +/- R's just fine on any machine but any chapter marks I add are invisible to other DVD players unless I use the RW style discs. And this has held true with my first Magnavox machine, a MWR 10D6 and when that conked I replaced it with another MWR 10D6, same problem. Then, I recently upgraded to a MDR513H with a hard drive and still, that one produces DVD-/+R's with chapter marks that can't be read by other machines. It makes me wonder if there is a step I am missing that I can't find or comprehend in the instructions. I mean is there a step before finalization that would have these chapter marks be read on other machines. I stick with Magnavox because I am used to their editing system and in general they are good but this has always been a mystery.
