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

[dev_nul]

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
