Ok ive labelled this as Distributed as flash is avaliable across all OS's but the content im looking at is really UK only as it involves the BBC. My current HTPC is an old laptop (well not that old as it runs vista rather well) connected to my Samsung TV outputting 720p and im having difficulty telling if there is any difference between the BBC's high def iplayer streams and the usual "higher def" content they've started pumping out. The HD stream is listed as 3200kbps and it does indeed consume a fare old whack of my internet bandwidth when playing but dispite this, as i said, i cant tell the difference when compaired to the 1500kbps stream that you get for the other channels. Anyone else notice this or is it just me? granted the HD stream is very taxing on the laptop so maybe that has somthing to do with it.
