Thanks for the help.  So are you saying that I won't be able to change
channels in myth?  I was thinking I could tune the PVR250 to channel 3
or 4 (or wherever I find the signal from the cable box) and then use an
IR receiver and serial port to my cable box (motorola) in order to
change channels.  I guess I am not entirely following what you are
telling me though I appreciate the help.  I am also not clear on why I
would tune to channel 10 instead of 3 or 4.  If I were to plug a TV into
the coax out of the cable box I would have to be on 3 or 4 wouldn't I?

Thanks again,
