WOW!!! Bob11879, you are the MAN!!!
After I changed the drive into PIO mode, I got PERFECT movies!!! Also, it allowed me to upgrade the firmware!!! What the hell is going on with my AMD chip? Damn!!! I really spent too too much time on that. Thank you all so much!!!
BTW, does this mean I have to use PIO mode for this driver forever? What the advantages of DMA? Much faster? Anyhow, for successful burning, I have to stick with PIO mode for now.
Is this a bug of Plextor driver with AMD CPU? Why cannot they fix that???
