My first post just timed out and I get to write all this over again :a
Anyway, having problems w/ my tdk 840g firmware 1.08. Happened with 1.07 too. All problem burns have been movie backups w/ dvdshrink 188.8.131.52, usually using all the disc. In November I started using memorex 8x dvd+r (Ritek R03). Just recently found out the discs have playback errors. Looking at the back they also all have burn rings - sometimes two almost complete circles, some kinda cloudy. Previously I used imation 2.4x dvd+r with no problem. No rings, both kinds have purple dye.
I don’t get any errors when burning - using prassi at 8x or roxio 6 at 4x and 8x. Cannot reshrink any of the memorex. Can disc copy /copy files with windows explorer on a few of them, but not with most. Some playback ok on my newest player and computer, but most have errors on all three of my players and on my computer. Thinking it was the media I returned it, but tried a tdk 4x dvd-r that came w/ the burner last night and it too has rings and doesn’t playback right - burned at 4x w/ roxio.
So now I’m worried it’s the burner and of course my one year warranty just lapsed. Gonna try a sony disc my friend burns w/ no rings tomorrow hopefully. Does anyone have any ideas or suggestions? Should I go back to a firmware that I know worked? Is there a way to clean a burner? Thanks for any help.
