Replacements for steps steps 2 and 3.

a. Change the grabber for your existing video sources to None.
b. Add a new videosource from Schedules Direct for your area.
c. Connect all of your inputs to the new video source.
d. Scan for new channels.

Reusing or deleting the old videosource will corrupt some non-critical
but still visible information for your existing recordings.  I'm going
to correct that in v31.
