Reported on test forum by, Sentinel confirmed by FlipGer & ronilse
Tested with MediaPortal 0.2RC4 + svn-06-30-2006--01-41

If you have in MP setup selected an analog Radio station to start playing when MediaPortal starts up, you will get an error message that WMP can't start it. If you then open the same Radio station in My Radio it starts just fine & no problem.

h4. Additional Information
To reproduce:
1. MP Setup -> Radio & mark an analog Radio station to play at MP launch, then Close setup again &,
2. Start MP -> you now get a message that "WMP cannot find the extension, etc". Click yes, nothing happens...
3. Go to My Radio & select the same analog station, it now plays just fine...

If you select a Internet Radio stream instead, it plays just fine at MP launch.
