Tagesschau.de not supported

[Mono]

Some videos at the site http://www.tagesschau.de (German news) play just fine, but the most important one does not.

navigate to http://www.tagesschau.de, then hit "Letzte Sendung" (which means: most recent video) and "Video starten".
The flash file starts to play in terms that the audio stream plays as it should. Without any more user input it plays until the end. But the video does not play, it does not even start.
When moving the mouse over the video area, the stream stops with the following message:
----
 We're sorry, Lightspark encountered a yet unsupported Flash file
SWF file: http://www.tagesschau.de/resources/tsplayer.swf
Cause: Unhandled ActionScript exception
Press C to copy this error to clipboard

[Mono (mono-g)]

the above applies to lightspark version 0.7.0 on the OS Trisquel 5.5 which is a derivative of Ubuntu 11.10 Oneiric Ocelot

The stream is started but doesn't show on screen, maybe some other component is being draw on top of video or the video's size is zero.

When the mouse is moved over the play button or other controls, an exception is throw because gotoAndPlay is called with non-existing frame label.
