You're probably noticing the problem most often on NFL games carried by your local network affiliates. Because D* has to carry the local affiliates for so many different cities, they compress them about as much as possible, resulting in a soft picture and problems capturing motion. So what you're seeing is normal and to be expected from NFL games on local stations. The good news is that because all your DirecTV Tivo does is capture the original satellite stream and store it, the Tivo preserves the original quality, i.e. there is no quality loss with the Tivo compared to the live signal.

In theory, analog cable can always deliver a better signal. In practice, many/most cable systems don't. Which is why DBS systems are around.

The right answer is to get an HD Tivo and an antenna, then get the HD signals from all the local stations....
