Very good point, and it's true, most of that 250 GB is tv XD I'm going to do a quick test install of Mythbuntu to a partition - running it without a tv tuner is an 'unsupported configuration', but anecdotal evidence seems to be that it works out okay. It's got a nice frontend for organizing and displaying files, works with media center IR remotes, and apparently can be set up to run transcoding jobs while it's idling, despite the fact that it's main functionality is DIY PVR XD
