I saw Ubuntu TV at CES and I also spoke with the developers that would be working on it. I saw would be because, what was being shown was a mock up. There are several unknowns at the moment. What will be used for the actual DVR functionality, how/where to get guide data and what the actual UI will look like. While I wish them well, Ubuntu TV has a way to go before you can go down to your local electronics store and buy one.
