It is completely possible to switch in Live TV from a non-DVB card to
a DVB card, or vice versa. Press Y to chance cards, and C to change
inputs (i.e. tuner/comp/svid on PVR350) on the current card. You can
alter which appears first by altering the card's/input's priority I

As long as channels are setup correctly in myth (if using 0.18 and a
channel scan is successful you are almost there) you must ensure that
the XMLTV ids are suitable, and that the start channel for each input
is set to a channel that actually exists (DVB channels can have
non-consecutive numbers when can be confusing).

I find using phpMyAdmin now invaluable in locating and resolving
problems on my myth box, especially when channels are not behaving
