I'm looking for something similar, edit out certain fragments with edl
mplayer -edl fragments.edl source.mpg -dumpstream
but with this I get the WHOLE stream.
Without -dumpstream an older mplayer version plays what I would like to 
have in 1 file.
I've been reading on stdout and named-pipes, but I don't get it.:-(
Someone any idea howto accomplish this ?
