There are a pack of LiveTV fixes just being backported from master to
0.27 at the moment, so it is probably better to just ignore LiveTV
problems until the fixes have been fully tested and arrive in 0.27.
Which seems likely to happen in the next week or two.

So what I would do would be to manually adjust the channel LiveTV
starts on.  This SQL command will show how things are at the moment:

  select cardinputid,cardid,sourceid,tunechan,startchan,livetvorder
from cardinput order by cardinputid;

The livetvorder field tells you which tuner will be used when you go
into LiveTV (unless it is already recording).  The lowest number there
is the first tuner used.  The startchan field tells you what channel
number will be tuned to.  So something like this command should fix
your problem:

  update cardinput set startchan=1 where livetvorder=1;

That presumes that your livetvorder field has been numbered starting
from 1 and that TV One is on channum=1.
