[MPlayer-users] Some problems with my DVD-drive

[Green, Shaun]

Thanks for the DMA info. Unfortunately, I've already installed Mandrake 9.0
on the hard drive that had Red Hat 8.0 on it. It seems better, because it
doesn't have all the Bluecurve mess, but it will take some time for me to
test and see if I can install Sawfish and Mplayer.

My stable MPlayer setup is still Red Hat 7.3 for now.

Problem solved, problems occured because of that fact, that Redhat
disabled all DMA-support for CD/DVD-drives.
To enable it in Redhat 8.0, and in order, to use mplayer fluently, just
add this line into /etc/modules.conf:

options ide-cd dma=1
