Ok this has me completely baffled.... i ust wiped my computer about 3 months ago... i have XP pro. everything was working fine, i burnt several cd's on my lite-on 24x and 10+ dvds on my tdk. then about two weeks ago, i started having buffer problems, it goes to about 20 then drops to 0 and stops burning for a second or two. it takes 9 friggin minutes to burn a cd! the same happens for a dvd. they are both on their own IDE channels, my hdds are on the RAID channels. i updated ide drivers and everything, but no help. i heard that using dma helps, but i never did before, and i dont think its compatible if you use RAID... i tried everything to get dma working, added the reg dwords and all... any suggestions?
