Anybody got an idea what else I could try?
I have the exact same drive, I've tried Ritek, Ricoh, Princo, Maxell and Verbatim DVD-R media (I don't use DVD+R - mainly because it's not quite as widely supported yet) - the only media I've found to run at 8x so far is the Verbatim media (even though the other brands are 8x rated they only run at 4x in this drive). As for Dual-Layer media, Verbatim is the only brand that appears to be sold Down Under - AUD$13 per disc and it works fine at 2.4x.
By the way, I had two models of Teac burners before I got the Nec ND6500A, they were the DV-W22E (2x -R) and the DVW24E (4x +/-R) and they had the same problem. With these earlier drives I'd tried Ricoh, Princo, TDK, NEC, Imation and Verbatim DVD -R and +R media - and with each drive only the Verbatim media would burn at full-speed, all of the other brands burned at half speed (1x and 2x respectively).
So I don't think this is a problem with the drive necesarilly, but more likely a problem with the quality of the media - Verbatim is the most expensive of these brands and generally regarded as the highest quality media, in fact if you study the dye and substrate of each brand of media you can see the difference in quality quite clearly.
Basically if you want to burn at full speed, use Verbatim (but if you find another brand that works I'd be interested to know).
