I've been on the BBC Interactive Media Player Trial http://www.bbc.co.uk/imp/ in the UK which is a superb way of keeping up to date with BBC Programming.  It allows the download of TV programs to your PC and also to mobile devices such as Windows Mobile Smartphones, Pocket PC and Portable Media Center devices. 

I discovered this blog post today  which talks about one persons experiences with IMP.
