I'm getting a permissions error with get_iplayer. I'm using ubuntu
12.04 running in an oracle virtual machine. The
/media/sf_iPlayer_Recordings is an external windows folder mounted to
the unix machine

kevin at kevin-VirtualBox:/media/sf_iPlayer_Recordings$ df --si

The question is what does this message mean "Permission denied at
/usr/bin/get_iplayer line 3939"

Thanks
