I would like to set up a Hopper on a Dish 500+ for 110/118.7/119 with second dish using a DPP LNB for 72.7 (obstruction problems with 129). This would normally be done using a DPP44 switch. It looks to me that in addition to the DPP44, you need to connect a solo note between the switch and the Hopper. Is this correct? Also, given that 72.7 carries many of the SD channels available on 110/119 (and maybe even a few of the HD) will this mess up the channel guide? Thanks in advance for replies.
