Just another comment (still not time to setup and try your advice)... I
have notice that MythWelcome says that I have 3 tuners while I only have
one. I get messages like Tuner 1 recording, tuner 2 idle and tuner 3
I have a Nova T-500 dual tuner...any idea? Can this be the cause of the
above weird behaviour?
