OK Vangelis.
I agree.
It's not worth upsetting things just for the sake of <1MB. :-)

... Though if we were designing the get_iplayer script now from scratch it might be worth considering FFmpeg metadata to reduce the dependencies and simplify the Windows installer.
(Perhaps FFmpeg's tagging capability was introduced after get_iplayer was invented)
