No worries man, XBMC once set up will pretty much blow anything away with its interface, any "borrowed" movies you may have open up in an ultra slick interface thats ripped TV/Movie posters off the internet. All your medias displayed like cinema posters, gives you nice plot summaries of EVERY movie and TV show, cast, director etc.
You can also use it to stream netflix, freeview channels and any "live streams" wink wink through it, ive pretty much replaced my sky box with it.
Also you can buy a Microsoft Windows Media Center remote in Maplin for a tenner, pop the USB dongle in your XBMC machine, windows installs it automaticly and thats you, works perfectly for navigating around XBMC.
And this is all just in the standard build lol, the mods/skins for it are ridiculous and has a massive community support.
Cant really recommend it enough
If you go down that route mate, gives us a shout how it goes, happy to answer any questions about it cause its ****ing awesome. Also makes life a lot easier for the family to watch all my "borrowed" media lol.
