@NINVIN21 - hmmm, so it sounds like the BYX5 firmware does recognise those discs but you still can't use them ?. it could possibly be worthwhile you cross-flashing. i'm not sure what to recommend tonight though as i'm done in and i don't want to trash your drive; could you read up on it some more and i could have a look at this again in the morning when i'm (hopefully) fresher
Great link for firmware. I don't know if they work after crossflashing. I don't understand czech language. Maybe there's an english readme in the archives.
I've used this thread to research my Sony DVD DW-D22A drive. I had the same problem where my burner continually failed to write a DVD...it always said invalid media. I updated my firmware from BYS2 to BYS3 successfully; however, I still receive the same error messages. I completed more research and bought different brands of recordable DVD's and recordable speeds: Maxell DVD-R 8X, Memorex DVD-R 16X, and Verbatim DVD-R 16X.
I haven't tried the DVD+R recordable discs. Should I? What speed should I get? Should I try to upgrade to BYS5? BYS6? Do I need another .exe file along with the BYS updage?
