In my experience, the HTTP streams generally work more reliable than the RTSP ones. If you want the m.yourmuze.fm site to give you the HTTP streams instead of RTSP, you can trick it into thinking that you're using an iPhone by changing your browser's user agent string.
Oele, your neat trick seems to no longer work. If I set firefox's user agent to masquerade as an iPhone I still get the rtmp stream. I REALLY REALLY would like the .aac stream for my PC to avoid rtmp's aggravating gaps of silence.
Is there some other trick I can adopt to avoid rtmp? Why don't you make it easier for users to select the tcp stream? Perhaps by a setting on our login page at m.yourmuze.fm?
