That wasn't them, that was me :) I updated the grabber so that
anything recommended by the RT was given maximum star-rating (but
different metadata to show it was a RT choice, and not a film rating).

What is the output from

# mythbackend --printsched

for the House entries? It might make things a lot clearer as to why
your rules are not working as intended. We need to see what the
'final' priority is for your recording rules (that is not always the
priority you assign in the rule). If you have an assigned additional
recording priority to all Power Searches, it could cause the final
rule priority to trump your regular House rule, and win out.

(I'd also recommend upgrading to 0.21-fixes if possible.)
