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.)
Why might this be?
"mount" is suid, so it's run as root even though you're logged in as a regular user. xine and mplayer, on the other hand, run as your user.
Briefly put, check the permissions on /dev/hdc and make sure your user has enough permissions to use it
This for me involved adding myself and my wife who uses the box as part of the disk group I believe before I could play a dvd. -- Johnathan Bailes BAE Systems ESI "UNIX was not designed to stop you from doing stupid things, because that would also stop you from doing clever things." - Doug Gwyn ---
