IPlayer caching again

[#1]

Trying to watch F1 catchup and keep getting caching.  Wireshark shows all is normal as to traffic, tried 2 gateways so far  pcl-ag04 and a new gateway ptw-** cant remember which one.
I have plenty of speed to stream IPlayer, 
using Opera 11.62 and latest Flashplayer tried with and without hardware acceleration enabled.
Anyone else?

F1 catchup is streaming fine for me. Gateway ptn-ag03, using Firefox 11.0.

It seems to be ok for now, not had caching for last 10mins or more
