Chanid's are a primary key. If you do not delete your Video Source 
entries, the new ones will be higher numbers and your chanid will not be 
1002 but 6002 *for the same channel*.  Exactly what you do NOT want.


If you delete all the video sources and recreate them in the new setup 
in the same order ( Cable was '1' and is recreated as '1') then the 
chanids will be duplicated.

If you KEEP the video source then numbers will all be wrong.

Then you should seriously consider following the preferred route...

I am not sure. I will have to take a look at the database on the mythbox 
at home. I know 'Previously Recorded' matching is done at least on on 
title+subtitle, but it may use chanid as well somewhere in there (don't 
think so, but it could).
