I even switched the antenna wires between boxes and no change.Looks like the second tivo will be on hold and use the CM 7000 for a while. I only use that to record on days when I record 3 or 4 channels at the same time.
After using my new Tivo for less than one day, I also experienced the crappy tuner issue. The first tuner seemed to worked just fine, the second tuner worked fine for channels below RF channel 20, but would only intermittently receive channels that were above it. Apparently I may have some multipath issues that I have never had to deal with because the DTVPal, Sony DHG, my Samsung TV, and an old LG Tuner have always handled any multipath issues. I called customer service for an exchange, because I presumed tuner #2 was defective. They proceeded to tell me it wasn't the Tivo, but my antenna that is incompatible with the Tivo. They told me that my antenna didn't have enough "power" to drive both tuners (that is really what they told me). I insisted on an exchange anyway, which they were reluctant to give me. I really gave them no choice, because I was either going to get an exchange, or I would return it for a full refund.
After setting up the exchange, I did a google search on 'Tivo tuner issues', and found that a lot of people have issues with the Premier tuners. The general consensus seems to be that they do not handle multipath well. Apparently the older (non-Premier) Tivos had much better tuners in them. I realized that this exchange is probably a waste of time, and my new one will probably have the same problem, and it may even be worse (at least I had one tuner that worked without an issue). I am still waiting on the exchange to get here to see how the next one works.
