Yeah, all RITEKG05 disks show the same behavior.
I think it is random. I was trying disc by disc, all of them are RITEKG05, all giving the same error. But then I selected Nero to Simulate before burning in 8X, and it worked, very odd
I have used LG dvds, no problem with them. But with these RITEKG05 I am having these problems. I think it depends of the dvd mood to burn.
