Okay I got the specs:
It's a NEC ND-2500A 8x series burner.
The media is US Digital General Purpose 8x DVD-Rs M40104.
I think I may have it solved the problem. Last night I did burns at 2x and couldn't notice any flaws on the playback. Previously I had burned at 8x and noticed many errors. Even though the media and burner are rated as such is this a common problem?
