Not only that, Channel 4 make a large quantity of their content available on 4od(nasty flash site but still vaguely usable in linux) for 30 days, or indefinitely for stuff in their backcatalogue, such as the comic strip presents and every episode of peep show, whereas the BBC keeps recently aired content online for 7 whole days and expects you to buy the DVD if you would like to watch anything older... If i miss the first episode of a programme and realise this just after the second episode has aired i then have to go and torrent it before watching ep2 on iplayer. Now i keep an eye out for things and just rip everything remotely interesting with get_iplayer, resulting in nice mp4s that i can watch later, as in whenever i like, and without suffering the appalling performance of fullscreen flash.
Another great move by the BBC is to offer drm-free downloads of iplayer content, but guess what, you ordinarily(get_iplayer can retrieve these, thankfully) need to own an iPhone for them to extend this functionality to you, great, huh?
