Ok, I have some more data about my problem. I don't know if I expressed 
exactly what is my problem, I'll try to be more specific. I run a movie 
under X by command
mplayer -vo xv /mnt/dos-d/Movies/Videoclips/Black\ Eyed\ Peas\ -\ Hey\ 
Mama.mpg

And the output looks like this:

And after a while it goes into something like this:



            ************************************************
            **** Your system is too SLOW to play this!  ****
            ************************************************

Possible reasons, problems, workarounds:
- Most common: broken/buggy _audio_ driver
   - Try -ao sdl or use ALSA 0.5 or the OSS emulation of ALSA 0.9.
   - Experiment with different values for -autosync, 30 is a good start.
- Slow video output
   - Try a different -vo driver (-vo help for a list) or try -framedrop!
- Slow CPU
   - Don't try to play a big DVD/DivX on a slow CPU! Try -hardframedrop.
- Broken file
   - Try various combinations of -nobps -ni -forceidx -mc 0.
- Slow media (NFS/SMB mounts, DVD, VCD etc)
   - Try -cache 8192.
- Are you using -cache to play a non-interleaved AVI file?
   - Try -nocache.

The problem is that top show 10% CPU usage and about 2.1% of memory 
usage. I'm really sorry for long posts. Hope it can help you.
