[MPlayer-users] dumpstream ?

[openman]

Hi.

I want to ask how to get only concrete part of file as I get by
Mediaplayer.
E.g.

On page

http://www.ceskatelevize.cz/vysilani/1176221164-uvolnete-se-prosim/24834-dana-kuchtova-karel-nespor-sasa-alias-madonna.html

there is link to file

/vysilani/videoscripts/playlist.asx?porad=1176221164&format=WH&add=1&rlink=http%3A%2F%2Fct1streaming.visual.cz%2Fnew%2Fasx%2Fhigh&linkarr=Uvolnetese-220906.asx'

But in my dumped stream file is some *.wmv which is very big. About 3
hour of duration. Useful for me is only 40 minutes.

How to command mplayer to strem from, to any frame or time?

Thanks

Oleg
