Picked up Windows XP Media Center Edition 2005 and spent the better half of my day installing it and trying to get it to work with my digital TV card (VisionPlus DVB-T). I'd say that after a LOT of work, I'm three quarters of the way there. I got it to detect my card but a scan picks up only 2 of our 5 free to air digital channels.

The drivers I am using with my card are still in BETA so there is still plenty of room for improvement. Here are a few (tiny) screenshots of MCE 2005 in action.
