I can't find the email right now, but I believe I saw recently that
one of the devs was working on some changes to allow commercial
detection to run simultaneously with recording rather than running
after the show has been recorded.  His main goal for this was to allow
watching of shows with commercials marked as soon as they are done
recording, but I'd imagine this would go a long way towards your goal
of muting commercials.  You might want to wait until those code
changes get committed or at least coordinate with whoever it is that
is coding that feature.
