I use Memorex DVD+R media, I just started attempting to back up my dvds. I tried to back up my "Da Ali G Show," and when I used Decryptor it seems to write the file ok. When I burn, however, and verify the data is says there is some kind of data error, and the begining part of the dvd plays but then shuts off. Is this probably because of my media or is it the sign of something else? If it is the media, any suggestions for what kind to get?
