P.S. regarding language.
XBMC is !!free!! and super popular software that puts all your music, TV, Movies, pictures, etc into an awesome full screen menu on your TV for searching and playing. It plays pretty much any audio or video format without any fuss and it's actually a breeze to install. My issue seems to be a rare thing.
If you have an old beater PC or laptop to spare, it's an awesome way to select and play all your AV stuff from your big screen. If you run it on Linux, you can truly use an old beater of a PC and just add drive space if you have a lot of movies to store. For simplicity, the Win7 version is identical.
It's normally super, super easy to install and use. Don't let the 'language' above scare ya.
