Hallo
I recompiled my mplayer with openGL support:
prompt# mplayer -vo help
MPlayer dev-Fedora-GS-CVS-051128-18:25-3.4.4 (C) 2000-2005 MPlayer Team
CPU: Intel Pentium 4/Celeron D Prescott; Xeon Nocona (Family: 15, Stepping: 3)
CPUflags:  MMX: 1 MMX2: 1 3DNow: 0 3DNow2: 0 SSE: 1 SSE2: 1
Compiled for x86 CPU with extensions: MMX MMX2 SSE SSE2

Available video output drivers:
....
	gl	X11 (OpenGL)
	gl2	X11 (OpenGL) - multiple textures version
	dga	DGA ( Direct Graphic Access V2.0 )
....

I also checked whether DRI is used:
prompt# glxinfo | grep direct
direct rendering: Yes

And I run mplayer with a command
prompt# mplayer -vo gl2 -vf tfields ~/movie.mpg

I can see that it does not have "mice teeth" (so deinterlacing works), but it is incredibly slow. I wonder what is the reason.

1) video stream is too big ?
  PEG-PS file format detected.
  VIDEO:  MPEG2  720x576  (aspect 2)  25.000 fps  8000.0 kbps (1000.0 kbyte/s)
  ==========================================================================
  Opening audio decoder: [mp3lib] MPEG layer-2, layer-3
  AUDIO: 48000 Hz, 2 ch, s16le, 384.0 kbit/25.00% (ratio: 48000->192000)
  Selected audio codec: [mp3] afm: mp3lib (mp3lib MPEG layer-2, layer-3)

2) mplayer does not use DRI drivers, but some software emulation (how to check it)
