Some programs still seem to be missing

[Nick Payne]

get_iplayer isn't indicating any errors when I refresh the cache with 
--refresh, but programs that I can access through the iplayer web site 
don't appear when I search for them in the cache. For example, the 
iplayer web site is showing me that there are 17 programs covering 
Commonwealth Games weightlifting available, but when I search the cache 
with

get_iplayer --long weightlifting

only one program is found, and that's not a specific weightlifting 
program but just part of the general live coverage.
