Hello everyone, I currently have FIOS and have a premiere elite. It works perfectly. I may be moving soon and here on Long Island FIOS is not available everywhere. Where it is not available I'm sure I would end up with Optimum/Cablevision. My question is: Will a premiere ELITE work on Optimum/Cablevision's system? Are they digital only? By work, I mean able to use the 4 tuners as I can now, along with work in general. Thanks in advance.
