like http://www.tvinfo.cz/stranky/stream11 Maybe there are using some fancy way of caching or redirecting the URL See https://bugs.edge.launchpad.net/ubuntu/+source/totem/+bug/112183 for the Launchpad bug reports that with other examples.
It's a buggy mmssrc.
That website resolves to mmsh://wm.dist.nacevi.cz/CT24-High?MSWMExt=.asf which plays perfectly with git everything and playbin2 (but not with playbin).
