Hi Lars,
A cursory look suggests the problem originates in Firefox's internal decoding, even using the most-recent nightly builds. Furthermore, the problem only is apparent when the video is played from within a Commons page ( http://is.gd/mWpoap ); viewing the video directly works just fine ( http://is.gd/gn0BEr ).
The previous version of the same film (with a slightly higher bitrate) hangs during playback for me, even from that kind of URL, http://upload.wikimedia.org/wikipedia/commons/archive/d/d4/20110216144655!M%...
This happens more often if other programs are running in the background, so apparently its a competition between available CPU power and bitrate, that makes Firefox go into deadlock. It doesn't "degrade gracefully".
I tried to submit a "support question" on mozilla.org yesterday, but today I can't find my question there. I don't know how that is supposed to work.
I made a poll at the Swedish Wikipedia village pump, http://sv.wikipedia.org/wiki/Wikipedia:Bybrunnen#Videoproblem
All videos work fine: 6 users, running either Firefox 3.6.13 on MacOS or RedHat Linux, Firefox 4.0 beta on Windows, Chrome on Linux or Windows.
Very few videos have problems: 2 users running Firefox 3.6.13 on Windows Vista.
Many videos have problems: 4 users running Firefox 3.6.13 on Ubuntu Linux, IE 8 on Windows 7, Chrome on Windows 7.
No videos work: 3 users running either Safari on Mac or IE 8 on Windows Vista.
