The new Flash 10.1 beta uses DXVA (DirectX Hardware Video Acceleration). However it has problems with scaling right now. The main reason they didn't do this earlier is because of paranoia about buggy video drivers causing crashes and potential security issues. This is windows-only right now (presumably because Apple won't give Adobe access to the necessary APIs). When DXVA goes into the main player, iPlayer should be able to improve their HD encoding parameters (e.g. turning CABAC on, more reference frames etc.) However I doubt this will happen because the streams might well end up looking better than the broadcast albeit only at 25p. - Sent via the backstage.bbc.co.uk discussion group.
