Does the HR34 require a stronger signal than a HR20? The reason for this question is that I have an installer coming with a HR34 and another HD DVR along with an upgrade to SWM coming on Tuesday. I currently have a HR20 and a old Hughes legacy receiver hooked to a 5-LNB Slimline dish via a legacy multiswitch. I have levels varying from the low 80's to mid 90's on all the needed transponders. Thanks in advance.
