I'm assuming the nanostick is the DVBT2 device, giving you access to
the extra HD channels not available on the 2250?

If so, I think you should have two video sources, one connected to
both the channels on the 2250, and the other connected to the
nanostick.  The nanostick's source will contain all the same channels
as the 2250's, plus the HD channels.

In the backend setup I would recommend giving your cards and sources
meaningful names (rather than accept the default) which helps when
connecting source to tuner, and also makes troubleshooting easier if
things go wrong.

Having done a channel scan on each capture card I then run a script
(attached), slightly modified from the one on the wiki, which assigns
visibility, channel number and xmltvid values to each channel based on
their callsign.  Note that I use xmltv data for the mainline TV
channels and EIT for the radio channels and some other TV channels of
borderline interest.  My channel list is likely to be slightly out of
date (new freeview channels seem to appear and disappear from time to
time) and you may have different channel visibility preferences.
(tv_grab_uk_rt has a 'listchannels" option which will show you what
channels are available).

I run mythfilldatabase externally using cron (script attached).  I do
a single tv_grab_uk_rt run, and then two mythfilldatabase runs, one
for each source.  I presume that if you configure mythbackend to run
mythfilldatabase then this is taken care of for you, but I'm not sure
how.
