Exactly.

If channel/video source/input connections configuration is your problem, 
you can "start from scratch" by simply going into mythtv-setup's Video 
Source section and choosing "Delete all video sources", then re-create 
your Video Source(s), re-connect inputs, and re-scan/-fetch channels.  
There is absolutely no difference between doing this and starting with a 
completely blank database--except for your not having to re-configure 
everything else in MythTV.
