But even if it wasn't available, it still should show up in the guide.
The channel guide for 129 is a bit confusing.
One line says its available on transponder 31 but right below that it says the same thing but not available.
That's because it is mapped down to 130 from two different higher channel numbers. Take a look at the 9400-9500 range on the HD channels on TheList, you'll see it available and mapped down to 130.
If you do not have the channel in your subscription you will not see it mapped down in your guide and in the red color (of the HD version). Scroll up to the 9400-9500 range and do all channels, you'll see it in Red on 9529.
