What am I doing wrong

I am trying to make backup of my DVD’s. I am using DVDShrink and AnyDVD what happens is everything burns well but when I go to play the DVD it gets all digitized and just stops playing. I am using Ritek 4x DVD-R’s and Oppirite DD0203. This just started to do this in the last few DVD’s I have tried to backup. Any thoughts?

What do u mean by “play the DVD it gets all digitized and just stops playing”?
is it on ur dvd player 9 stand alone or the dvd drive?
If its ur dvd player (Stand alone), how old is ur dvd player?

To my notice it would be ur dvd player problem because some dvd players get confused when reading some dvd, even the original ones. Try ur burned dvd on freinds dvd player ( Stand alone) if they are able to watch it with out any problems, that i am certian that it is ur dvd players problem.
