I would say the same thing to you about Fox. They are both good, but I think Fox does it better. As long as it looks good I don't care.
All FOX stations put out the same signal so same multi-casting is the same across the country, unlike CBS which varies by station. Some local markets look like garbage but the unmolested ones are unmatched. There is a pretty good consensus on most web forums that CBS is tops in PQ and when it comes to the NFL, FOX is a good notch down. Now maybe your display isn't large enough or you sit to far away and that could explain things.
But I will agree with you about AP.
Negative. All Fox stations do not multicast. I know one nearby that runs at 17mbps.
Since FOX is 720p60 they do not need the whole 6MHz to transmit their HD signal, many stations use it for a weather channel.
Correct me if I'm wrong, but I think all FOX stations use the same splicer system and the signal coming to each affiliate already has a chunk cut out for the multi-cast channel. Now the site may not add in their multi-casting but the PQ is just the same as if they were.
Here is a link discussing the issue....

And from FOXeng specifically "And no, I don't expect anymore bandwidth than the 16 max "
I don't know the last time I looked 70 inches was considered pretty big, and just like CBS all Fox stations get the same signal but not all Fox stations multicast ours doesn't and if 70 isn't big enough I can go up to 103 with the projector, or down to 60 with the Sony but like I tell everyone else it doesn't matter what anyone says as long as it looks good to you.
