I had the week from Christmas to New Year's off, so I was able to spend some time investigating a couple strange events. One that I noticed was that if I am using my Colossus input card to watch directv and Media Center needs to change the channel on the directv box to record a show, the OSD is not updated with the new channel. It will still show the channel I was previously watching. It doesn't appear to be a problem, but it is a little annoying.
