how about just making the west coast HD feeds (CST/EST only) time zones MPEG4 and making them 5:1 per QAM and same for east coast HD feeds in California but that won't even be needed as California is now probably not going to get anything due to frontier taking over in 2016 along with Texas and Florida.
How about making all of them use H.264. That would be much better especially since they are broadcast that way to begin with. Instead FiOS has to muck them up and convert them from H.264 to MPEG2.
