VIA chipset? I had redhat/mandrake running for a while too, but I did not test those as well as I have tested gentoo (I love gentoo) so I cannot say if the problem existed on those distro's, but I'm 100% certain is was alright on winblows. Tried damn many things, changed pci slots, removed cards, compiled different kernels, changed the burner's settings, changed the harddrives settings.. nothing has any impact, I firmly believe it is a software issue.. I have put together computers for about 12 years now, I like to think that I know something about the hardware now and I firmly believe it is a software issue. I've been told some have had trouble with the grease inside their cd-rom's vaporizing or accumulating too much dust, I guess I'll take a look inside it as a last resort, but I doubt that lack of grease is the cause. My burner is very new. - Kim
