Removing phantom tuner in MythTV

I had a tuner that did not appear on the tuner screen in setup, but would always throw an error about the default channel for it not being available when saving and exiting.

In order to resolve this, I followed the suggestion here: http://lists.mythtv.org/pipermail/mythtv-users/2010-March/284826.html

1. manually login to the database
1. mysql --user mythtv --password mythconverg
2. find the phantom cards id
1. select * from capturecard ; 
3. delete it from the 'capturecard' table
1. delete from capturecard where cardid = ;
