Choosing the 'Delete All' options for capture cards and video sources
is the best way to clear out your old settings.

Increase the verbosity of the backend log to include the channel and
record log options, and see if you get more useful output.

Have you specified a channel to tune to (rather than a valid starting
channel) as this can break channel changing?
