I've been burning DVDs and ripping them for a couple years now my computer and just recently, the rip times won't go higher than 1.7x and the burn rate says it is 16x, but it takes almost 40 minutes to complete a burn with Nero (as opposed to about 6 minutes previously). What could cause this kind of drop in performance? I checked the DMA mode on my DVD drive, and it says Ultra DMA mode 6. I don't think I installed anything new, certainly not any new hardware, so I can't figure out why this would happen for apparently no reason. The DVD drive is a Sony RW DRU-810A, using the standard XP driver. Any help would be appreciated.
