Hi there, I am trying to use the Windows Media Player ActiveX control host as described on this page:

http://msdn2.microsoft.com/en-us/library/aa446515.aspx

It works fine in my device emulators, but when I try to run on my BitsyXb dev kit I get a "Class not registered" error. with this stacktrace:

System.Runtime.InteropServices.COMException was unhandled
Message="Class not registered "
ErrorCode=-2147221164
StackTrace:

at System.Windows.Forms.Control._InternalWnProc()
at Microsoft.AGL.Forms.EVL.EnterMainLoop()
at System.Windows.Forms.Application.Run()

Hopefully this isn't a total newbie question, but can anyone assist? If you'd like to try reproducing it, just grab the demo from that webpage and run it.

Thanks, Ian
