I've changed the DVD drive on my SuSE 8.1 system to be IDE instead of SCSI emulated, and enabled DMA. Now, the system doesn't lock when I try to access the drive with DMA turned on :-)
However, even though I can mount data CDs and even DVD movie discs in this drive, I can't play movies - even the same disk I've just mounted (when it's not mounted, of course!). MPlayer complains "Couldn't open DVD device: /dev/dvd", and xine just does nothing. I've linked /dev/hdc (the DVD drive) explicitly to /dev/dvd ("ln -sf /dev/hdc /dev/dvd") but the same thing happens. (It was linked to /dev/sr0 before I got rid of ide-scsi on this drive.)
My earlier note suggested you turn on DMA, but I missed this one :-) On my PC, I had to retain the SCSI-emulated link - setting /dev/dvd to /dev/hdc would not work; MPlayer wouldn't start. why this should be I have no idea, but I assume there is some config file somewhere that saw /dev/dvd as SCSI at install, and still wants to see it that way. If you have machine lockups when you have SCSI emulation, and are using DMA, I'm afraid I don't know what advice to give. I would have thought all DVD drives were sufficiently recent to support DMA, so there may be something else afoot with your system. Kevin
