I recently hooked up my vip 222 receiver to receive dish 110,119, and 129. I'm using two dish 500's, one with a dishpro plus dual lnb for 110,119 satellites and the other with a sinle lnb for 129 satellite which is hooked up to the additional "lnb in" from the dishpro plus dual lnb that I am using for the 110, 119 satellites. It works fine in the main satellite 1 tuner on my reciever but when I use the signal splitter to use the second tuner and run a check switch, the second tuner does not work. How can I solve this problem so that I can take advantage of the second tuner to use with another television. I understand that I'm not going to get HD channels out of the second tuner but I just want to get the regular non-HD channels.
