After some extra reading on from googled links (usually, a really waste 
of time) and experimenting, now I have two more comments. How accurate - 
I am not sure.

1. No good documentation on how to use mplayer. Or, rather, so many 
options on command line that are hard to understand that one can get 
crazy very fast and go back to windows rather.

2. I suspect that my video card, which is somewhat outdated (ATI 
Mach64/3DRag) might be the source of the problem with video.

However, I am able to get sound with mplayer with movies that had sound 
entirely crippled when using xine. But with mplayer I do not know now 
how to display video!

And I am able to play everything properly when viewed on Google Videos 
(flv files).
