I finally bit the bullet and decided to upgrade my old VIP722k unit. Instead of risking my life trying to go up a tall ladder and swap my DPP LNB (using single coax into the home) for a DPPH, I opted for the DPH42 switch instead which I mounted in my cable closet. The problem I'm having is with the satellite feed - I am only getting satellite 72 and not 61.5 (I'm on the Eastern Arc). I'm thinking I may have gotten a bad DPH42 right out of the box but looking for some opinions. Both 61.5 and 72 locked in fine using the 722k model so I feel like the LNB is fine. Only thing I'm not sure of is if the DPH42 needs both outputs from the existing non-hybrid LNB.
