I currently have two Zinwell 6x8 multiswitches, fed by power-passing splitters, feeding my five HR2x's. The only problem I currently have is with changing channels on the one HR20 that is fed from the Zinwell that is fed by the non-power-passing sides of the splitters. Most channels work fine, but for some, sometimes, I need to tune to that channel on another receiver first. So I'm wondering what my options are. Am I using the wrong type of splitters? Should I replace the multiswich with a 6x16? Or should I look into getting a SWM? I wouldn't mind being able to use my OTA antenna, and I only have two cable lines (or two per receiver in one case) running to most of the rooms. And there's the possible multi-room viewing feature to consider. I just don't know how involved and expensive the SWM option would be compared to the others.
