Flash redirection issue with iPlayer (and others)

Hi,

I've got an odd one I've not been able to find an answer to (I've got a support incident open too).

We're running 7.1 MR1 and are having issues viewing certain Flash streaming media, like iPlayer and 4OD with redirection enabled. BBC iPlayer content comes up with "This content doesn't seem to be working. Try again later.", this is usually after a good wait, like it's trying and times out.

Other media appears to work. Normal "youtube" content is fine, it plays quite well, and other arbitrary flash media out there appears to work correctly so I'm guessing it's down to how the on demand services stream. Also the iPlayer content appears to work with Flash redirection turned off (albeit very badly as there's no accelleration).

There's no firewall blocking anything.

Anyone had a similar issue?

Kind regards
