@mclingo, from my experience (I've not used it either, but I've worked with it), the reason that people aren't using MediaPortal is that it's at a nightmare stage of MediaPortal (not 2) is the more popular one, is stable, and has strong plugin and skin support, but has core flaws preventing future improvement. MediaPortal2 has a better system for more modern features like 3D, HDR, idk, but has breaking changes in the skin and plugin framework, not enough devs to iron out the massive changes it underwent, and has the catch 22 of no one will write plugins because the core doesn't work, but no one will work on the core because there's no skins or plugins to make switching worth it.
That's my uninformed, second hand knowledge of it. I personally don't like Titan (the only skin I've heard of for MediaPortal), and Estuary is fucking gorgeous (thanks Phil).
