I've been researching the breakage of playing back mmsh streams in rawhide (with the necessary 3th party plugins installed) and I've come to the conclusion that this is caused by totem no longer passing get parameters in an URL through to gstreamer: Using Fedora 9 with totem 2.23.2 (from Fedora 9 updates) opening the following url works fine: mmsh://av.rtl.nl/web/components/actueel/editienl/2008/week33/vr18.Editie_NL_15-08-2008.MiMedia_WM_1500K_V9.wmv?MSWMExt=.asf And using gstreamer debugging I can see the full URL gets passed to mmssrc Using the same Fedora 9 (and thus 100% identical gstreamer) with totem updated to 2.23.4 (from rawhide) and having the rawhide evolution-data-server parallel installed to the F-9 one for deps, opening the same URL, only the following part gets passed to mmssrc: mmsh://av.rtl.nl/web/components/actueel/editienl/2008/week33/vr18.Editie_NL_15-08-2008.MiMedia_WM_1500K_V9.wmv Notice the missing: "?MSWMExt=.asf" at the end. This breaks playback of mmsh video streams. Note I've also reported this upstream (which I know ends up at the same person, but I wanted to make this block the F10Target tracker).
Erm, forgot the upstream bug url which is: http://bugzilla.gnome.org/show_bug.cgi?id=545864
There's no point in filing an upstream _and_ a distro bug. The person looking at the bugs is the same (ie. me).
