I don't care about Fox cause DirecTV Gives it to me, they also give me CBS. But anyway, I am new to this, and maybe someone can help me understand this. In the channel guide for DirecTV it is showing me 4.1, 4.2, 4.3, 5.1, 5.2, 7.1, 7.2, 7.3 ... and so on.. What are these extra channels I thought I would just have like 4.1 and 5.1, so what are the extra ones like 4.2 and 4.3?
Thanks

In some cases, the local stations are sending multiple digital channels, for instance channel 5 sends 5.1 & 5.2. One is simply a digital channel broadcast at 480i and the other is the HD channel broadcasting at 720p or 1080i (can't remember which it is at the moment...) Is there a compelling reason for them to do this? Good question. I am not aware of one.
Channel four even throws in 4.3 which always seems to be a shot of the SL skyline with a radio station playing in the background. Whatever.
My concern would be that these channels might be constraining the bandwidth available for the HD feed.
Maybe Ken can chime in with his thoughts since he works for KSL.
