That was exactly my point, although of course I was assuming that the 60 Hz 
issue continues to exist. Cliff disagrees. If the issue doesn't exist anymore, 
then ATSC already allows for 24/30/60, so it would be up to broadcasters and 
networks to stop using the odd rates in production. Same sort of thing which 
also applies to interlace over ATSC (or DVB-T). When its reason for existing 
goes away, essentially with CRTs, it can simply be dropped.

Whether that's true or not, I would say that apparently no one was considering 
*why* the odd rates were being retained, until Cliff yesterday, responding to 
my post. I saw a lot of careful explaining how inconvenient the odd rates are 
in production, which is not in dispute. Cliff seems to believe that there is no 
reason to retain the rates even for analog transmission, so of course that 
would change things. But again, ATSC does not mandate their use. It just allows 
it.

Always happy to oblige!
