OK, the plot thickens:

My Tecra M2 laptop is running 10.1 RC1 and the xgl stuff - it plays all the
videos with no problems. The graphics on the laptop is (from lspci):

nVidia Corporation NV34M [GeForce FX Go5200 32M/64M] (rev a1)

The problematic desktop has the following graphics (from lspci):

nVidia Corporation NV18 [GeForce4 MX 440 AGP 8x] (rev a2)

An older chipset it seems, and it crashed on every attempted video playback,
until some googling turned up some hints leading to successful video playback.

If I say "mplayer dancemonkeyboy.mpg" it crashes instantly.

However if I say "mplayer -vo x11 dancemonkeyboy.mpg" it plays solidly,
whether being dragged around the screen, made transparent, played on the
corner between 2 desktops or what have you.

So clearly, some finite dimensions of the problem have emerged. I know that
for some reason linux vendors won't ship anything capable of playing any
popular video format, which might cause this to be disregarded, except that
the problem also exists in the real player, which is shipped with suse, when
playing *rm files.

So, is this already a known issue, or have I stumbled onto something obscure
with my particular hardware?
