Recursive download with episode name filter?

[Nick Payne]

For example, with the coverage of the current world snooker 
championships, I'm only after the videos of one specific player versus 
another, and they all have episode names of the format A_v_B, where A 
and B are the players.

BBC have a pid that can be used to download all their coverage with 
--pid-recursive, but I'd like to filter it down to only episodes that 
contain "_v_" in their name. Is this possible?
