Before I had a Sony DRU-500AX that only wanted to burn my Ritek G04@2x. So I did a pretty good deal and swapped it for a NEC 1300 that burns all my Ritek G04@4x. Did some checking Nero CD Speed and disovered this withe the exakt same media. (tried a couple with same result)
NEC 1300 with Ritek G04:
Sony DRU-500AX with Ritek G04:
Does this mean that the NEC have som quality issues at the end of the DVD? Anyone can post there result so I can compare? Should I write Nec support about this and let them investigate for upcoming firmware upgrades? Burning with the Nec at 2x doesnt help, it only makes the read performance unstable all over the DVD instead of only at the end.
Hoping for some good answers.
