XMPCR isn't made anymore, XMDirect is an easy plug-in (though the online vendors rip you off for the cable required - build it yourself if you can solder) and other folks have commented on the Sirius setup.

Depends on the station. Both providers are lacking for bandwidth on the sats and as a result, compress the heck out of (and vary the encoding bitrate of) all the stations. The Electronica stations seem to be the best (i.e., they use the highest bitrate/least compression) and the talk stations (comedy, news, sportscasts) are the worst. The choices make since if you think about 'em, but it sucks overall.
The rock stations are "ok", the country stations are worse than that, the classical stations are about on par with the country stations.
The real issue (to me) is the quality of the _programming_. I've been an XM subscriber since 2003 and their programming has really declined over the years. The rock stations seem to be in a 2 hour loop. The Electronica stations are pretty stale, and the news stations are riddled with commercials.
Sirius's programming has dropped off as well, but they're better off than XM.
Also, the XM/Sirius merger has been approved, so the question of "who's programming is better?" will soon become "when will I be able to get a multi-sat receiver?".
