I got a couple new burners a while back and put my old 1100A in a friends PC. It's been running fine for over a year now. Suddenly I discovered it will only burn at 2.4x on any media we've tried. I'm using Taiyo Yuden 8X +R and Maxell 8X +R. These discs have burned just fine at 4x in the past, but suddenly DVD Decrypter and Nero both report burn speed at 2.4x only. I did notice some kind of DMA issue. I went to open DVDFab Decrypter and it said DMA was not enabled, but to all appearances in Device Manager DMA most certainly IS enabled. Regardless I deleted the channel and let windows reinstall with no luck. It still lists as DMA Mode 2 but burn speed is still 2.4x. I did have trouble reinstalling the channel though. I kept getting at error that the IDE driver was incorrect for the OS. After disabling the drives themselve as rebooting the IDE channel seems to have setup correctly. DVDFab Decrypter also no longer gives the DMA message. Any input on all this? He swears his problems started when he first tried to back up Sin City, but that may well be coincidence.
