Automatically launch WMP to stream .asx (Orb) TV

[PFM]

I am using a Pocket PC running WM6 and trying to connect to my Orb TV stream. It should launch WMP (10) when I connect in pocket IE but instead I receive an error telling me that "A file with that name already exists. Do you want to replace it?" I can reply yes and then go to WMP and browse to the file to launch the stream but would really like it to be automatic. Is there a registry edit to do this?

Thanks,
