I just installed my 3500A in a Dell Dimension 8400 and when I try to burn a DVD it is really slow and the device buffer keeps going up and down. It will only burn at about 1.4x.
I've checked the DMA and it appears to be okay and my DVD-ROM works great ripping to the hard drive.
I also have the Windows XP 64bit version with dual boot and it works fine.
If anyone has any thoughts on this it would be greatly appreciated.
BTW, I have tried several firmwares and I am now using the NEC 2.19 with RPC1/RL.
