Quite a while since I did a post, and things in the TVHeadend and XBMC world have moved on quite a bit. TVHeadend is now being actively developed, primarily resolving the EPG issues that were around in the past, but then also moving onto loads more improvements. Therefore things have moved to a development environment, so if you want to try out the latest you can on github.com/tvheadend. Or via the original www.lonelycoder.com site where you can get debian packages and official releases. Hope you like all the updates!
A few people have also asked me about the dev stuff I've done, I've got a few testing areas for TVHeadend at my own github (http://github.com/andyb2000/) so take a look, and drop me a note if you want to try anything out as I'm always looking for new testers, or join the TVHeadend lot on IRC freenode.net #hts
