Only show a guide with hd channels

[Gustovier]

When I tried Microsoft media center for a couple of days it had this great feature that allowed you to show only hd channels in the guide. That would be great here as well. Now I don't think there's an actual facility within sage that let's u know if the channel is an hd channel. So you might have to get crafty and maybe filter out any channel that isn't showing a show flagged as HD. I realize this won't be perfect cause their possibly could be times when an hd channel broadcast a show that doesnt have the hd tag. This Is just one thought of doing it.
