Lately, I've been having trouble playing burned DVDs on my DVD player (Sony DVP-S560D). At first, I thought it had something to do with my Mac, but now I'm starting to see the problem with commercial disks. The main symptom is that the player gets "lost" while playing the disk, and particularly when changing menus, and flashes the wonderfully user friendly "C:13:00" which means "disk is dirty". But of course, it isn't. My DVD-Rs play fine on the Mac, and they used to play fine on the DVD player, but what used to be an occasional drop-out has turned (in about a 6 month period) into almost unplayable DVD-Rs. I've heard those DVD player "laser cleaning" devices are a hoax, but I'm starting to get desperate. DVD players are so cheap, I'm not sure its worth it to have the thing professionally serviced. Anyone have any experience with this sort of thing? The player is maybe 3 years old - do DVD players croak that quickly? Thanks, SR
