In the configurations i can select either 'DTV-DVB 3054 Digital TS Capture (TwinhanDTV Ter(D+A) DVB-T)' or 'DTV-DVB 3054 Analog Video Capture (TwinhanDTV Ter(D+A) Analogue)'.

I have a working aerial plugged into the TV card and am trying to scan in UK freeview. When i select the Digital capture card no channels are picked up on the scan. When i select the analogue capture card it says it is unable to create a graph for this device.

Any help would be appreciated, thanks.
