Got it as a cheap upgrade to be able to Play DVDs at full speed, wich the old 600mhz Athlon couldn't (amazing). Maybe it was just the Gfx card, an old Riva128Zx.
I have a silly question.. Did you activate the DMA for the dvdrom?? The dma for cdroms/dvdroms in windows are usually running without dma as default, and this would cause the dvd playback to be choppy.. I have had no problems playing back dvds even on a old pIII 450mhz.. A 600mhz athlon should definitely be up to the task.
