Facts:
Plextor drive artifacts when connected to my Supermicro motherboard, on playing, and on writing with AnyDVD HD to the hard drive.
In other words, what is coming out of the DVD player, into the computer, is corrupted, even when it's NOT playing on the screen.
The corrupted ISO's play just like the disk through the player.
I connected the Plextor to the HTPC, and installed DVD 8, did the upgrade, and it plays
fine. This with an Nvidia 9600, and corresponding software.
I'm in the process or ripping to ISO one of the disks, and, once it's ripped onto the hard drive, it should mount in virtual drive, and play fine on my machine.
That's the theory anyway.
It sure is slow ripping...
Next test is to try playing the iso on the ATI 4670.
