Much like the chap that posted on this very forum about his Pioneer DVR109 giving him the "DMA-driver error, CRC error" I began getting the same thing (my burner is the DVR-111D). This change was sudden and completely unexplainable. Naturally, I figured it was the burner...so I swapped it out for another one lying around (an NEC) and got the same error. I tried the blank DVDs I was using on another machine, they work. I tried both burners on another machine, both work. At this point, I figured it had to be something gone wrong with my Windows install. I recently got Vista and behold, the burning still is no-go. At this point, I can only conclude that the problem is at a hardware level, on the motherboard...or can I? The one exception to this is that when I try and use DVDxCopy (which I only use to backup my own material) it works!! Anyone have an idea of what I can do? I don't have two burners in the machine, so setting it to slave isn't an option. I'm just stumped and very fatigued on this one.
