Sorry, I'm a bit oldscool and still think of my wrappers being AVIs - being
a bit Visual Basic 3! I meant WMV.
As the iPlayer downloads the complete file before playback, there is no
requirement to stream.
Conceptually you have a file wrapped up like this:
( < { [audio]+[video] ] VCodec } DRM > WMV )
The VCodec the BBC use is WMV9, I was presuming it was the WM9 MPEG-4 based
codec because of the quality and bitrate, I havn't got a file to hand to
check however...

Eh? The iPlayer content is WMV format, WMA 9.1 and WMV9 with the MS DRM
implementation. I always thought because WMV files are ASF-based, and
streamable, they were discrete audio and video streams within the WMV
wrapper?

David,
The files transferred using iPlayer are just .AVI wrappers of MPEG-4 type
content. The DRM is inside the AVI wrapper, outside of the MPEG-4.
