I respectfuly disagree. Having those west feeds helps me to avoid sheduling conflicts. Especially on Sunday and Thurday nights when I have both tuners recording from 8 to 11.
At this point, it makes sense for the premiums to start scheduling with the DVR users in mind. They should be repeating their primetime premiers a few hours later in the wee hours of the morning. This would let west-coasters pick it up in primetime and allow DVR users (on both coasts) to pick up real-time viewing at a reasonable time. The primetime window is fairly small, so repeating it on the same channel would be somewhat easy.
This would eliminate the need for duplicate channels for each coast. The space used for the duplicate channels could be used for more programming, more than making up for the programs shifted out of the late night hours on the original channels. A few channels have drifted toward this way to handle their schedule for a while now. Outside of primetime, does anyone care if premium channel content is shifted for the west coast or east coast?
