I downloaded a WMV from iPlayer tonight, and served it from my PC to my BDP5200/05 (f/w 1.31).
I tried to play it - didn't work (authorization problem).
Then I played it on the PC, which fetched a DRM licence. Probably should have done this before trying to play on the BDP?
Anyway, it still didn't play - same error.

Has anyone persuaded this to work?

(PS: the reason I downloaded it instead of just using the built-in iPlayer is that - bizarrely - you can't rewind with the NetTV iPlayer...)
