I can burn to RITEKG05 DVD-R discs (have been doing it at 4x) however once it is complete the verification fails because of unrecoverable read error. I used to use TDK DVDs before this and had no problem with them, and they can still be read now by the drive. I have taken the discs to work where i have a new acer machine (not sure what the drive is) and the RITEK disc that i burnt at home works. I will check another disc tomorrow at work to confirm, but this seems like a strange problem.
I’ve had a quick look on these forums, and i am not up to speed with all the lingo just yet, so please try to explain what i can do with some detail.
