I use MajorIdiot's mythchanger script to change channels on my
SA4250HDC, with my HD-PVR as the tuner. I do not have a firewire tuner
set up, I just have the mythchanger parameters in the section that
asks for the external channel changer. I'm at work so my description
might be a little off; If you'd like I can get an exact description of
what's set up where when I get home.
