Hi,
The installer is correct, the tuner in your PC is for terrestrial TV signals (dvb-t) and not cable signals (dvb-c) so it would not work. However, if your PC has composite video in, you could hook the box up to the PC with a SCART to RCA cable which would mean you could choose the channel on the box and then record it on the PC. Basically your PC is acting as a hard disk recorder though obviously what you are recording you would have to be watching at the same time.
Hope this helps,
Ben
