No specified modes

[gary]

I'm a new get_iplayer user. I've tried windows and linux. It works for 
radio, but not video.

I saw a post about a new (patched) get_iplayer.pl on the archives to get 
around the "no specified modes" error when downloading BBC video. I got 
the latest get__iplayer.pl and still have the same problem.

I run it just as a command line
(perl get_iplayer.pl --get 123 --options),
dumping the media to file. Any idea why I get the "no specified modes?"
