It seemed to be a short outage - I've used it since this post and all seem to be working. Let us know how the mythtv installation works out. For my last build I ended up using the mythdora pre-built installer image.
http://www.mythdora.com/ and I'm very impressed. My remote worked right out of the box (only after I discovered that my cable connection was loose) and the installer takes care of installing the base system as well as all the things required for myth to just work.
