Yes, run FFmpeg from the command line.
Open the "dos" window, Start -> run -> cmd
Then change directory (cd) to C:\Program Files\get_iplayer\FFmpeg\ffmpeg-0.8-win32-static\bin
Then try a command:-
ffmpeg -h
See if you get a response.

Then try to convert the file.
!!! The command I gave you before is wrong!!!
Don't use "-c copy".
Try a command like this instead:-
ffmpeg -i filename.partial.mp4 -vcodec copy -acodec copy filename.mp4

Maybe you will need to put the partial file into the FFmpeg\ffmpeg-0.8-win32-static\bin folder temporarily.
