[MPlayer-users] cannot play with -vo xv

[rpolach at atlas.cz]

Sorry, this is a bit offtopic:
I have tried play with -vo xv and got problems.. so I have read docs and
have try xvinfo. It says "no adapter present".
But I have ATI Rage 128 AGP that HAS XV SUPPORT in X!
There are also messages that Xv loads in X logs.
Can anyone help me? What is the problem?
(I know: this is NOT mplayer problem, so sorry again)
(X 4.1.0, kernel 2.4.8, MTRR enabled, Mandrake 8.1)
Thanx a lot for help
