    On my machine (Windows 7 64-bit, Intel Pentium 4 3GHz, 1GB RAM) HD video is only watchable with hardware acceleration support provided by the graphics card.

    Good news: my graphics card provides the H264 support needed for iplayer HD content.

    Bad news: Adobe Flash plugin 10.1 refuses to use it because of an issue with the headers on the iplayer HD streams.

    Good news: some kind soul has created patches to bypass the Flash header check which means I can now watch streaming HD in iplayer. Nice.

    Bad news: iplayer desktop doesn't support hardware acceleration so downloading HD programs is no go for me - very very jerky video, unwatchable.

    Modern graphics cards are specifically designed to play HD video without hammering the CPU - it seems a bit odd for the bbc to have created an app which doesn't exploit such support. Does anyone know if there are plans for a desktop app which rectifies this? Or maybe this just isn't an issue for most people?

    Flash: Its an issue for quite a few - for example (and there are others, also over at Adobe's forum).

    It sadly just appears to be being ignored :-(

    Air: thats even stranger, why adopt a program build structure that appears not to use H/W accel at all? (If I've understood correctly from other places) I guess they assume everyone uses modern quad core CPUs, and "tuff" if you don't.

    Not that it helps much, but have you looked at the Windows Media Player downloads? they appear to play OK at least. Not sure if all the progs have them, but some do on the iPlayer Beta site at least.

    I was hoping that someone from the BBC would comment on the why's and wherefore's but so far, no joy.

    Unfortunately, the one download format that isn't offered on HD programmes is WMV, so Desktop is the only option for downloads at the moment.

    From what I can tell, both Adobe and the BBC can't agree on who's responsible for sorting out the problem.
