I'm sorry. You are correct. I misread Alan Pergament's column. DirecTV does offer home games in HD. Same as TW. Road games against NYC area opponents (NYR, NYI, NJ) are also in HD on both. And any game picked up by NBC later in the year.
So the only difference is Versus and Versus HD. DirecTV is in a dispute with Versus, so it doesn't offer those games. 6 of the 7 Versus Only games remain.
I never had DirecTV but the other things that moved me to TW from the Dish were: surcharge because I didn't have a land line on Dish ($5.99) vs bundle discount with RoadRunner on TW. And those annoying weather outages on Dish.
