Like everyone else who bought an HD Ready iDTV[1], Freeview box, or
DVB-T card for their PC in the UK, you'll need to buy new DVB-T2
tuners in order to receive HDTV over digital terrestrial when
launched. I'm not aware of any supported DVB-T2 tuners on the market
at the moment. The LinuxTV wiki is worth bookmarking when researching
supported hardware [2]

Recording DVB-T/Freeview is really quite straightforward - after a
channel scan to find your available channels, MythTV can download the
programme guide broadcast over-the-air (so no internet connection
required for this [3]) and record simultaneously from as many tuners
as you have installed. You may quickly find you get recording
conflicts that multirec cannot handle [4], so I would strongly
recommend getting 2 physical DVB-T tuners.


[1] iDTVs with integrated Freesat can receive HD channels broadcast
over DVB-S (not involving MythTV), but you'll need DVB-S2 tuners when
channels move over to that (DVB-S2 cards are already available)

[3] You can opt to use XMLTV instead to get your TV listings, but this
is currently more cumbersome to configure
[4] multirec allows MythTV to record simultaneously from a number of
channels broadcast on the same multiplex using a single physical tuner
