[mythtv-users] Picking up DVB-T2 HD channels with TBS6280 capture card

[James Stocks]

I want to be able to watch and record Freeview HD (DVB-T2) broadcasts.  I purchased a TBS6280 capture card for this purpose and installed it into a machine running mythbuntu.  I compiled and installed the latest drivers[1] from the manufacturer's website and I've been able to get MythTV to tune into the standard definition channels, but no HD ones.  I followed a guide at parker1.co.uk[2].  

I am able to receive Freeview HD channels perfectly with my TV's integrated tuner.  I see from my google searches that others have had success with MythTV and Terrestrial HD, so what's the trick to getting MythTV to recognise HD channels?  I'm sorry for the basic nature of my question, but I'm completely new to MythTV and DVB-T2 support seems quite new and undocumented - I feel I may have bitten off more than I can chew.

Regards,
James.
