That's using a development branch, not the main release.
Indeed, although corresponding builds are quite well available. One which is particularly well related to this forum is the xvba+pvr version.
What I find most lacking though is proper support for timeshifting. In the end I turned back to mythtv which looks not nearly as polished and as a distinctly sucking music player, but which handles TV (live and recorded) much better and more intuitively. I found mythtv also to be much more stable, but that may have been due to the fact that I was working with cutting edge devel versions of xbmc only.
