I also have DirecTV and am certainly not happy with the present situation. Where I live antennas are spotty at best.
However I do see where tomorrow's game is listed as being broadcast on AUDHD, channels 71 and 500 on Direct. As of noon today I am still getting a feed on AUDHD! Whether this will still be the case tomorrow or not is anybody's guess.
As of tonight at midnight Direct may be removing NBC from their service. If that happens that will leave only one local affiliate still available for DirecTV customers. Most of us are paying an exorbitant amount already for this service and are certainly not getting what we are paying for!
On the other hand, the owners of these local affiliates, Cowles and Sinclair generate their income from advertising revenue. i don't see a compelling reason for them to be penalizing these same advertisers from a potentially significant customer base!
There should be a fairly simple resolution, but, as we all know, when dealing with money nothing is ever simple.
