One thing I'd like to understand about the US aspect ratio mess is the

the cable companies, or do the cable and sat people create them? I had

DPs would begin composing for the whole wide frame. Of course, that was

the widely variable aspect ratio approaches, there is also a ton of stuff
out there that seems poorly rendered with interfield judder and badly jagged
