mplayer -vo x11 -dvd-device /dev/hdd dvd://1

/dev/hdd should be the name of your DVD drive. For maximum speed (if
your graphics card supports VESA 2.0) you may use the vesa output
driver instead of x11. You may improve performace by using the
"-framedrop" option, and/or the "-vc ffmpeg" option. That's DVDs
with MPlayer 101.

The PII version should play sound if everything else is OK. I
doubt it will until you can resolve the problem which is
hampering MP3 playback.

I don't think you said what the result of this was. Did I miss it?

Are any of these CD-quality? Does play give any warnings?

No. It may be worth a try, but I suspect that a newer kernel will not
help. The problem appears to be whatever is causing MPlayer to stumble.

No. Newer kernels still offer OSS. In fact, many do not even come with
ALSA drivers. My main point was that a newer kernel would probably
require less effort to get audio working in general.
