In the mythconverg database. the table 'capturecard' has entries for
all cards defined in MythTV. There is a field called 'defaultinput'
which holds the value of the card's default input (yours should be
Tuner for your PVR-150).

The table 'cardinput' holds entries for all inputs for all cards (i.e.
for your PVR-150 there may be Tuner and Composite 0 for example). The
entry that corresponds to your Tuner needs to match that defined in
capturecard as the default input. A field 'startchan' in the
'cardinput' table stores the starting channel for each input.

You can check these two tables to make sure they agree to your ivtv
and channel configurations. It may be easier though to enter
mythtv-setup and delete your capture cards (leave channels and sources
alone) and then re-add the card. The correct settings should then be
in the database from the start.
