PVR can't find Hornets' Nest?

[Philip Colmer]

I'm trying to add the Doctor Who series "Hornets' Nest" to the PVR but the
latter doesn't seem to be able to find it.

http://www.bbc.co.uk/programmes/b0183qz6 is the main link. I've tried
refreshing the cache but searching for "hornets", "hornets'" or "nest" don't
find a match for the programme. I've also tried searching for words from the
episode titles like "dead" and "shoes".

Is this a problem with get_iplayer or my search terms?

Thanks.

Philip
