This is awesome - I have to wait till I have a 0KB recording, and then mark
that channel as invisible in MythWeb every time I come across a new copy
protected channel. It would be awesome if this was incorporated into the
next version of MythTV, and if the inverse could run periodically, in case
some providers turn encryption off at a later date.
