Advertisements Can you PHONE order PPV with a Series 3 unit? I thought I knew the answer, but after dozens of calls to Tivo and Cox in Santa Barbara, I got about half yes and half no answers from each. I thought that the only reason you need two-way for PPV is to order. It seems that Cox should be able to enable any channel for any length of time. So why do the folks on the phone when you try to order insist that is not possible?
