Hmmm, seems a most significant part of story was omitted - this only seems to occur on SA STBs. OTA and direct QAM does not have the problem. It also appears to be occurring for some on other feeds such as ESPN. Both of these are sports feeds in 720P, so there is no 2:3 pulldown. It would be interesting to see if any other 60P video on FOX also has this problem.
MPEG encoding is not a strict standard but more of a guideline. ATSC has also had some additions since it's inception such as AFD. FOX has switched from Tandberg to Motorola encoding, and the network encoded feed is passed without re-encode through the affiliates. FOX is now using AFD, and I think its use was added after last years NFL season.
Incompatibility between equipment is nothing new. However, since the issue is pretty much confined to the SA boxes and no other decoder appears to have an issue with theses streams and the problem is occurring on more than one channel, I'd say this points to the problem being the SA boxes.
The cable companies are ultimately responsible for providing properly functioning equipment. They may try to blame the networks for the problem, but when is not occurring on any other means of receiving the same signal it becomes a weak argument. If it was an Apple product, the faithful would just accept it as gospel. I doubt that cable companies have that sort of fanatical following.
Having said this, I think it would be in FOX's best interest to try to identify if there is something in their stream that is causing the incompatibility. It may not be their fault, but viewers will see this issue as being connected with FOX. It would probably be a good idea for viewers to complain to the cable companies and remind them that their competition does not have this problem.

The FOX SD feed is encoded by the cable company as a down conversion from the station's HD feed.
