Yes. If they have to do 60-second locals, this works. True, you only get 7-8 seconds for each screen, but something has to give when time is so short.
Apparently, my DirecTV setup doesn't know what to do with the 60-second LF's. It showed two more screens (the 7-day forecast and the local radar) after the music had stopped and the OCMs had reappeared. So, you could say I got a 90-second LF "under the table."
