For those of you who got modded first-gen Xbox with XBMC on it - you can watch BBC iPlayer on it. The only difficulty is that each program will be downloaded in full before you can start watching it. No PC required of course.
If you never heard about iPlayer before, take a look at this page: http://www.bbc.co.uk/iplayer/
The process is fairly simple but requires some technical knowledge.
1. Download latest XMBC from SVN - search for t3ch in google and take the first link.
2. Don't forget to backup your settings (unless you want to start from the scratch, of course).
3. Unpack and install XBMC (take a look at readme file first)
4. Download the script from http://code.google.com/p/xbmc-iplayer/
5. Copy it to E:AppsXBMCScriptsiplayer
