This is something that has been bugging the back of my mind a few days: With the MPEG4 changes bandwith will still be a factor of what can be done with expansion of HD locals. Has something like this ever been considered: Broadcast HD feed from each major network, 1 for each time zone, with 6 major networks that is 24 channels. Broadcast all local channels in SD, which they are close to doing already. When airing something in HD, the box tunes the HD feed. When commericals come on the box switches to the SD feed, automatically. The only thing the local broadcaster looses is logos on screen and possible emergency messages. The SD feed would still be available to subscribers for access to emergency info. If the switch cannot be setup off the network feed data, the E* could have employees that throw the switch manually during prime time, etc. It would seem there has to be a better solution than trying to carry all HD feeds for all local area. Even with MPEG4 the bandwith wouldn't handle it.
