I have a LG H55N burner used to work great but now takes forever to rip and burn.I uninstalled DMA on both IDE controllers.Installed the latest firmware driver for the burner. No help. I was starting to believe that my CPU was dying but I don't have problems with anything else. I watch my Task Mgr as I use the PC, everything seems OK until I use the burner. It bounces between 3 to 6% of the CPU's resources anytime I use Shrink or Decrypter.sometimes it disappears altogether.I uninstalled and reinstalled both those programs, but it didn't help. WHY doesn't the DMA seem to work. The burner doesn't get Direct Memory Access, it hardly gets any. Is it possible the CPU won't allow it because it's dying? If I replace my Pentium 4 processor,will that fix it? Can you test the CPU? Oh and I did buy a new burner, no difference. The PC is about 6 years old and we always kept it on.I cleaned out all the junk (unused programs,etc)and disconnected it from the internet so I could uninstall my Virus Program. Works great except for ripping and burning.I have HP Pavilion 751n , Petium 4 CPU 1.80 GHz 1.82 GHZ,736 MG RAM. I'm running Windows XP with 80 GB storage, 40 GB are free. I have a 300 GB external storage drive where I download everything to. I'm using Sony 1-16x DVD-R's. I was on a previous thread.
I would flash the old firmware back.. it's not always the best idea changing it unless there is a specific reason. Just follow the dma restore guides that are all over the place.. probably a fault somewhere with XP .. some drm off a game or something.
No, I did the DMA thing a half dozen times. I'm pretty familiar with it, it has worked in the past. The burner is on the secondary IDE channel and even thogh it says Ultra DMA Mode 2 for Device 0 and Muli-Word DMA Mode for Device 1 as Current Transfer Mode. It's not getting DMA.
