sds910:I finally gave up, as the entire process of accessing XM via the MCE interface along with XM's clunky software was completely and totally annoying. These days, I access XM via my own rewritten version of the Yahoo! Widget Engine's XM Tuner Widget. It's driven completely by my remote control, does not require having MCE's interface running in the background (yet has the same look and feel as MCE) and -- more importantly -- WORKS.
How about sharing your code? I'm sure others would like to use it.
