It depends on your burner. If you have a BenQ DW1620, or an NEC 3500a you will get some VERY good results. However, some older drives, especially with older firmwares, do not burn the media well.
Emperor: You place the fault on the media I see, but from my experience the media is actually quite good, but was poorly supported in previous drives. I'm sure you'll see with new firmwares that Optodisc is becoming quite a rival even to Ritek and Prodisc
(well, maybe not their DVD+Rs....)
One word of warning... I have reason to believe (but still no confirmation) that Radius may be using downgrade Optodisc media for their brand. I still haven't been able to pick some up for a direct comparison, but it's on my to-do list.
