That would interest a small portion of the country, maybe it would be a regional channel ... Much like the Longhorn Network.
What is on it ?
Hmmm, Looks like the channel is on in the cities I'll be in, in Texas next month, I'll have to check it out.
Brownsville, McAllen, Harlingen, Port Isabel (not available in PI or SPI, but will be going there as well).
Where in Texas are you ?
It's regional for Texas and I doubt DirecTV would be allowed to authorize it for anyone outside of Texas if they were able to carry it.
