If I type in

mmsh://mediasrv-the.musicradio.com/LBC1152?MSWMExt=.asf

on Linux, it plays correctly with no problem.

If I try to save the same link on the N900 media player it states invalid URL.

=. is a proper expression, the same expression works on Sydney's The Mix, Capital in London and so on.

It is definitely mmsh:// not mms://
