I hadn't actually installed MythTV and played with it before. I just installed it on my laptop.
Wow, this has to be one of the slickest free software projects I've seen yet! Installing from the Ubuntu packages was near idiot-proof, though it helps I already had my TV tuner going (which involved sticking a firmware file in an appropriate location).
Once installed and running, it Just Works. Everything is extremely polished, and you can tell it would work well with just a remote to control it.
Can't wait to get my server going and recording stuff! I think the GAF on this will be pretty high.
