[mythtv-users] How do set channels preferences and link channels with the tv program guide

I have finally got my two usb dvb-t cards to deliver reliable video from a 
common aerial.  So I am now into the phase of trying to make mythtv work in a 
backend/frontend configuration.  I am in the UK near the Crystal Palace 

In mythtv-setup I have created two cards, and a single video source which both 
cards link to (I assume that is correct?)

In the video source, dialog, for XMLTV listing grabber I use United Kingdom 
(alternative) which tells me its using tv_grab-uk_rt to get the listings.  I 
also have the "Perform EIT Scan" checked.

My first problem, is that selecting this brings me into a terminal window in 
which I have to say "yes" or "no" to hundreds of channels, whereas my cards 
only have about 30 odd channels they tune to, and even less that I am 
particularly interested in.

Is there anyway to simply select a small subset of the potential channels to 
allow mythtv to see on the tuner, and to limit the tv_grab_uk_rt questions to 
just those channels.  I really am NOT interested in stuff like "Bid-Up Tv" or 
even CBBC

Secondly, regardless of the first answer, is there anyway to order channels in 
the user interface so that the higher priority ones (ie BBC 1, and ITV1 etc) 
are grouped together and the lower priority ones (such as BBC NEWS 24 or 
whatever) are out of the way.  This is particularly annoying whilst watching 
TV, and to select between the two you have to go via a number of pretty 
irrelevent channels.

[I don't mind doing some poking around with SQL to achieve this if necessary]

Thirdly, there seems to be a mismatch between the channel name as provided by 
the tuners and that provided by the XMLTV grabber,  for instance, my tuner 
calls BBC 1 "BBC ONE", where as the grabber calls it "BBC 1".  As a result I 
have program listing for BBC1, but can't tune to them, AND an entry in the 
program guide for "BBC ONE" for channels full of "unknown".  The implication 
of the user interface is that if I go into the channel editor and select the 
BBC ONE channel, and put "BBC1" into the XMLTV ID field.  But I tried that 
and it didn't work.
