yes.
also noticed, that these streams has lots of zeros or repeating shit - not
normal in a valid stream. i'm pretty sur ethe bug is somwehere in teh mms://
streaming code.

> that the mms part is ok since dumpstream works... and that the codec is broken
there are no error checks in the current mms:// code at all - so it will
dump shit even if nothing to dump.

> since it segfaults even when I play the dumped stream.... :-/
yes, and not only mplayer crashes, try with avifile or xine or whatever
and running with -v -v you'll see many stream errors reported before it
crash on an unrecoverable error.
