DVD Burner is a Pioneer 105 Firmware 1.30 (original)
Now for the story.....I purchased a spindle of 100 DVD's (I know I like to gamble) and every one burned great, worked on all my stand alone DVD players, Xbox, PS2 etc. :bigsmile:
Purchased a second 100 spindle (heck the first one worked) and now the DVD's play very poorly in my stand alones, picture freezes in one and in the other there is pixelyzation.
Many trial and errors later (software version rollbacks, re-install drivers, check hardware configurations, check UDMA settings, burned at different speeds) finally decided to compare with known good media .........................
Took me 2 days to finally figure out the DVD's were the problem.
1 obviously a manufacturing issue with the dye;
2. will some kind of firmware upgrade fix my problem too, I have the Pioneer 1.33 2x4all file but really didn't need it since everything was working fine. I would rather not monkey around with flashing the drive if I really don't have to.
Needless to say I will be avoiding the AN31 discs in the future, out of 200 discs I'm happy with half.
BTW, the data is still good on the discs they just won't play in stand alones. Play fine on the computer (Pioneer, and an LG combo) I was even able to copy a movie from a bad AN31 disc to
a White Top Princo and the disc played fine in my players, so the data is still OK just the damn discs won't play properly in most stand alones.
Software used includes Alcohol120%, or DVDXcopyexpress, or DVDshrink with Imgtool and then DVDdecrypter. Same results each time.:a
PSS did uncover an issue with DVDXCopy Express tho. I can elaborate if pointed to the correct forum thread, very interesting;)
