    Correct, slightly softer, not as crisp. TIVO output is 1080i.

    I also have the Mohu Leaf Ultimate antenna (the version that is powered by an electrical source) to use with my Tivo Premieres and Tivo HD. Glad there are at least two of us!

    My antenna source is plugged into a splitter left by the cable company in my basement. The splitter is powered by electrical source. From there, the outputs go to 3 different tv and Tivos throughout the house.

    I, too, think the HD quality is amazing with the antenna. I receive all the local channels great, and the odd sub-channels can occasionally be useful. Most of the time they are SD quality and old re-runs.

    I have a few channels that are low power that I receive clearly occasionally but usually receive them with audio cut out every 20 seconds and picture freezes and blocking. I haven't tested any of these channels by connecting the antenna directly to the TV, but I have heard that the Tivo tuner quality is better on the HD than the Premiere.

    This is anecdotal, but it appears to me that the HD tuner is more sensitive than the Premiere XL tuner. I have one of each. All this means is that you may have to supply a stronger signal level to achieve sync with a digital TV datastream. However once you do achieve sync, the quality of the video will not be different for the same OTA ATSC signal when you change from one tuner to another.

    Think of a TV antenna as having a Boolean function for digital TV. It either captures a strong enough signal with sufficient symbol quality to achieve sync, or it does not. Once you achieve sync the quality of the signal can not get any better.

    It is very likely that a better antenna and/or tuner will stop the breakup of video and/or audio observed with a marginal signal, but a better antenna will not make your TV picture sharper and neither will a $60 HDMI cable.

    If it works, that's a 1, if it doesn't that's a 0. Binary. Two possible results.

    Is it a 1 or a 0 when I get fluctuating result for low power stations (picture mostly okay; audio cut outs every 20 seconds)?

    That is a 0

    You either get a perfect picture and audio, continuously, or you don't. :)
