No doubt you're familiar with the BBC iPlayer: we've been closely following the product's development since its cross-platform launch a little over a year ago. Since then we've seen plenty of developments, including the release of a desktop client (using Adobe's AIR technology) and today is another notable date for the iPlayer project.

In a move that's likely to please a lot of users - and infuriate already-annoyed internet providers - the BBC has announced that High Definition downloads are now available via a new version of the service's desktop client. The client will detect the speed of your connection which will pick the appropriate bit-rate version depending on your internet connection. The HD content, available as ever to British residents only, is available now via the BBC iPlayer site and there's plenty more content promised including Doctor Who and Dragons' Den.
