Can someone explain to me what these are, and if they are a real concern? Once in a while, I will get a "possible UDF error" after verifying a DVD burn, and a "Miscompare at LBA" error after verifying a CD-R burn (which happens much more frequently).

Yeah, so I am not sure how to read these yet. But I get the impression that this is awful. I need some feedback. Oh yeah, let me throw in another question...is it normal for your buffer (not device) to remain largely at 0%?
