You'll need to remove either recording rules or program listings (i.e.
fewer channels, fewer days of data, ...) to reduce the number of rows in
Though ugly, the BUSQ (Big, Ugly Scheduler Query) seems to work (and
scale) for everyone else using Myth, so unless you have a particularly
large-scale setup (i.e. thousands of channels and hundreds/thousands of
recording rules each generating multiple matches), it should work for
you, too. Can you provide specifics of your configuration (# of
channels and #--and approximate type--of recording rules) so we can
determine if the problem is actually a Myth issue before trying to fix
the BUSQ (which, generally, no one ever wants to touch).
