After burning several DVD-Video disks on my Optorite DD0203 burner I noticed the following: some of these disks play very well at the beginning of the movie on standard home DVD player (Samsung C631P) and xBox, but after a while a mosaic garbage appears on the screen more and more often and finally the playback stops because the DVD player won't read the rest of the disk. The same disk plays with no such problem on Optorite. The home DVD player and xBox have no problems reading standard DVD-9 disks throughout the whole movie. The mentioned disks were burned with no errors, although some of them failed data verification in Nero after burning, but played on Optorite. Both Samsung and xBox are compatible with DVD-R media only (will not accept DVD+R), and I used the following media: 1x CompUSA (Optodisk) DVD-R, 1x CompUSA (Princo) DVD-R, 1x Memorex DVD-R (all burned at 2x) and 4x Ritek DVD-R. The weirdest thing is that I burn the same type and brand of media, and one disk plays well up to the end of the movie, the other disk will have the mentioned above problem.
Has anyone experienced this issue? Is this a problem with Optorite (not burning equally inner side of the disk versus outer), or the media? If it is an Optorite, does any Optorite do that or just mine? Has anyone experienced the same thing with other DVD burners?
