I was comparing the current channel listing on the XM website and noticed quite a few channels that weren't listed in the XMcache file which is distributed with RR. This is causing XM users to miss out on certain channels. So, I set out to make an accurate file. I ended up adding almost 20 channels, removing a few defunct channels and changing the names of some others that have been updated. I will try to do this periodicaly to keep it straight. I recomend setting the XMcache file as "read-only" just in case so that it doesn't get corrupted.
