maybe it was just a matter of time and a matter of different batches of RitekG04s. The latest suck big time now with the NEC1300A. They burn still great with my Pioneer DVR-105.
This is addressing rdgrimes and OC-Freak: Don't say that the RitekG04 are varying much. That's not the case.
Pioneer owners will not see any difference. Now- my NEC1300A shows now power calibration errors with the newest RitekG04 I have. Disc code is H4-2L...
Worked with older H4-2L and H5-4L with no problems. Had the lens of the NEC cleaned. Even disassembled it for cleaning. Did not help...
All I can say: Use Plus discs with the NEC1300A if you have valuable data. Don't buy the NEC1300A if you want to burn RitekG04 which is good, decently priced media.
The lesson is this: Don't go for the cheapest burner because you have to get expensive media. Pay the little extra money for the burner so you can use decent, reliable media. Sum up the total cost and you will see that the cheapest burner is not always the best deal.
