Does anyone else experience problems watching NASA TV on OS2008?

When I try watching the RealMedia-Feed in MediaPlayer, the best I get are a few seconds of audio (no video) and then it aborts saying "Unable to open. Media clip corrupted".

MPlayer (1.0rc1-maemo.27.n8x0) lets me listen to the audio part of the stream (isn't even crashing!), but still no video :/
Is there maybe another mplayer version around with proper real/rtsp support?

Edit: just found out that I used an outdated version of the kernel with rotation support that screwed up X's xv-extension... all fine now
