Capture Card Setup - Dual Tuner Card

Hi,

I've got a dual-tuner DVB-T card (TBS 6280).

In MythTV "Capture Card Setup" it shows both adapters:

/dev/dvb/adapter0/frontend0
and
/dev/dvb/adapter1/frontend0

Do I need to add both cards in "Capture Card Setup" and create an entry for each in "Input Connections"?

Also in "Input Connections" as they both use the same source for schedule listings I assume I only need to scan for channels on one of them?

Thanks

Nick
