Do you have a DVD Recorder? The simplest way would be to connect the HUMAX to a DVD Recorder with a SCART lead, pop in a blank writeable DVD, select "AV1" (or however your DVD input SCART socket is labelled) as the input channel, press 'play' on the HUMAX programme you wish to record, quickly followed by pressing 'record' on the DVD remote.
Note: this will NOT work for HD recordings as I believe they are encrypted.
The HUMAX-->USB-->PC-->DVD or HUMAX-->ftp-->PC-->DVD route will work as well but requires a lot more additional steps and software involvement.
