Some of the scheduling details are covered in
http://www.mythtv.org/docs/mythtv-HOWTO-12.html.  What you're
interested in is the overlap handling and i don't think that is
specifically documented anywhere except the mailing list archives
where it comes up occasionally.  The current logic goes like this when
two or more rules cover the same program:

  More specific rule type wins. (E.g. Channel Record > All Record)
  Higher findid wins.  (Somewhat arbitrary, but ties need to be broken)
  Earlier created rule wins.  (Ties need to be broken)

While checking the above, I realized that when comparing a non-find
rule with a find rule, it might not do the best thing.  The attached
patch changes the behavior so that a non-find rule wins over a find
rule.  It's untested, though, so please provide feedback if it helps in
your case.
