Comment(by subbyz):

 I have dug in and found a semi-reasonable workaround for this bug.  In
 scheduler.cpp's comp_overlap() function, add the following two lines
 somewhere before the final line (I tested it immediately before the final
 line, but it might be better to be higher in the list, like after the
 title or chanid test):

 if (a->recpriority != b->recpriority)
         return a->recpriority > b->recpriority;

 This gives a preference in the PruneOverlaps function to allocate
 potential recordings to higher priority recording rules first.  A better
 solution would be to key off of whether the rule is actually able to
 record programs, as this workaround still doesn't handle some possible
 cases very well, but the necessary info for a better fix doesn't appear to
 be currently available in the ProgramInfo struct.  So this seemed like the
 best solution without requiring fairly extensive changes.

 Tested, and works ok here as long as the overlapping rules are given
 different priorities, and as long as it is ok that the lower priority rule
 will never be able to record a show that matches the higher priority rule.
