I agree with Kirby's comments on the bandwidth allocation. More bandwidth is always nice, especially for 1080i content, but I think the core problem is more likely in the encoder. Either its settings, or its capabilities. Since they have tweaked it in the past to improve its performance, I am guessing it is capable of much better than we have been seeing. But, it appears to need a lot of care and monitoring.
Also, from previous issues with WWMT, I think that they monitor less on the weekends, when all these MPEG-challenging sporting events come up.

Or would that confuse receivers/tuners?
I think available frequencies are at a real premium. The FCC's goal with the conversion is to free up a lot of spectrum. So, I doubt they will be allowing any expansion.
But, after the conversion, I am wondering if they will really switch to an HD primary signal. I think they will still see SD cable and satellite viewers as their primary concern, and the only real change for them will be freeing up a transmitter at their broadcast tower. They'll still broadcast digital/HD, but it will remain unimportant to them.
I guess ultimately money talks, their paying customers are the people who buy the commercials. Once they can charge a premium for HD commercials, they will start caring about HD broadcasts. That will happen once the percentage of HD viewers goes up. -- Which is another interesting issue.. maybe if there were examples of the commercials getting bad macroblocking they would be more interested in solving the problem.
