Removing ide_scsi from my /etc/modules and doing a quick
reboot has removed the DMA problem for the DVD drive. But
still having DVD playback problems.
Unencrypted DVDs still play fine, but playback of commercial
DVDs gives me lots of libdvdread complaints about not being
able to crack the css.
Furthermore /var/log/messages is full of:
hdc:command error: status=0x51 {DriveReady SeekComplete
Error}
hdc: command error: error=0x54{AbortedCommand
LastFailedSense=0x05}
I'm googling like a madman, but not sure what to look for
now. Never had a problem with DVD on my other systems, so
I'm suspecting a compatibility problem with either the Epia
MII motherboard or the slot loading DVD drive.
Any other thoughts?
