I see a 751 CNBC and a 751 soccer channel both are the same channel.
I see this in my Guide:
751: Olympic Soccer Channel
752: Olympic Basketball Channel
When I use the guide to navigate to the CNBC 751, I get a black screen. Nothing. (I have CNBC in my package, the regular channel works).
Soccer channel works perfectly fine, the games look good. Basketball channel of course has no coverage yet, they start play on Saturday.
When I use the remote to go to 751 directly, I go to the Soccer channel.
I have no idea though, how the 751 CNBC popped up there. I am assuming its just a simple human error in setting up the Soccer and Basketball channels, and they will - soon - add channel remaps for the other channels.
