I'm assuming that you are going out to other tv's with the coax output of tuner 1. if this is so you can get a modulater. this takes the rca's out of the\sat reciever into the modulater, the coax out to either just one tv or multiple tv's via your coax ne twork.
you then find a channel you are not using set the mod tp that channel and view tuner 1 on thatt channel. i think the322 has\a\built in mod, actually if you have a option to set that built in mod to a\different channel, do that. you need one clear channel between, to get a clear signal. for example: fox is on chan 25 wb is on 30
you could us chan 27,28 ,23,32.
the mod are $50 and up.
good luck.
