Yep, there is a case-sensitivity with --version value that breaks 
downloading, but not searching.  Sorry - I should have checked both. 
Since you're using your own script, just force $opt->{versionlist} to 
lower case immediately after options have been processed if you want to 
avoid this in future.  Not sure, but I'll probably change get_iplayer 
similarly for next release.  Option values should be case-sensitive, but 
inconsistency between searching and downloading is not good.
