why are so many people including myself having problems burning with different Ritek dye media.
Asked and answered many times. Iy appears to be a combination of things coming together to cause problems for some drives.
1) Some NEC drive do not like reading G03/4 media.
2) Some G03/4 media is inferior to others.
3) Some NEC drives don't burn it as well as others.
4) Some combinations of drive/firmware work better than others on the Ritek.
Any one, or all, of these variables can cause the issues, #1 is likely the most common. In some cases, 2 or more of the variables will come together to cause problems.
I don't believe that "so many" people are having problems with them, just "some".
But you can rest assured that the root cause of the trouble is the media itself. The 2500A is not the first drive, by far, to have problems with Ritek DVD-R.
