I Used the HD organization option so my HD channels will show first. But which are my HD channels? And which are SD? I assumed the HD would show first and it would be obvious when the SD line up started as the numbers would restart at channel 3 (or whatever number it does). But it does not. I think it starts with my HD channels and then keeps going up. I have lost channel 11 knowledge network, it no longer appears on the guide. Where is it?
