I've just found an old email from someone on the 'nemesis' side of the
Iplayer development where he told me that - at that time (2009) - the Flash
plugin couldn't cope with 48k and downsampled it to 44.1k. So they'd got
the servers to generate 44.1k to send as they'd do a better job of it.

I'll try to find out if that's still the case. I've ended up deciding to
try and write a potted 'technical history' of the iplayer development. So
I'll take this elsewhere as not 'on topic' for this list unless people are
