I just thought Id share a few of my experiences with backing up my DVD movies. OK, hardware involved is a PC with Pioneer 106D writer, and 3 standalone players; Pioneer DV444, Toshiba SD230 and Samsung 709. Software is DVDShrink 3.0 (newest Beta) and Nero 6. When I got the writer, I backed up my first film onto a VERY expensive Verbatim DVD+R (single with case). Using DVDInfoPro, I have found this disc to have CMC dye. This works with no problems in all 3 of the above players. After that, I bought a pack of 25 cheapo printable 4x DVD-Rs, with what I believe is Infosmart dye. This is where the problems started. Written at 4x, they play back fine on the Pioneer player until a couple of chapters before the end, when they start skipping, stuttering and pixellating. In the Samsung player, they wont play at all - the disc gets ejected as soon as you press play. In the Toshiba player, no problems right the way through. At 2x, the choppiness as described above with the Pioneer player comes in a few seconds before the end of the data - usually in the credits. Again, no joy with the Samsung and perfect playback on the Toshiba. So to sum up, the Toshiba will play anything, the Pioneer player is a bit more fussy about its media and the Samsung is just being an arse. But whats causing this behaviour with the Pioneer player? At first I thought the dye on this cheap media couldnt handle being written to at higher speeds, until it played back in the Tosh flawlessly. Could the Pioneer be more sensitive to errors on cheap media than the Tosh? Id be interested in any other experiences like this so I can decide what to do now... Im not sure whether to stick with DVD-R and go for more expensive media, or switch to DVD+R.
