Openelec does seem to be the leading xbmc distro right now.

> 9. HTS TVHeadend can be "turned on" in openelec for a total backend and fronted solution on one Pi. I'm keen to test how well this really works as I'm a little sceptical about the Pi's ability to record multiple streams while I watch a Blu-ray sized movie. I'll get onto this once I have a tuner dongle free. HTS lacks some scheduling and management features so I don't think I'll switch just yet.

I've been running MythTV for 7 years and toying with the XBMC MythTV plug-in for a few years. It's at a point now where its mature enough to ditch the MythTV frontend. Finally, a frontend under 5W of power and $60!

Good contribution thanks, someone who is using one of these in NZ
conditions. Also if you are doing satellite as opposed to terrestrial
you will need to buy the MPEG2 codec. It's ghastly expensive... all of
GBP2.40 - and when I bought it they rounded down to the nearest GBP!
