I am trying to understand how and why this is functioning the way it is then also report and issue.

If you look at channel 693 it is mapping to channel 1251. If I hit the "Hide Channel" icon then 693 no longer shows in the guide but 1251 still does.
Also I cannot record on channel 693 but I can on channel 1251.
Any help clarifying how this works would be great.
Thanks
