I live pretty much in the center of a triangle of Houston, Austin and Dallas, Fayetteville, and I get service out of Austin, but my OTA antenna can pick up Houston HD signal thankfully. Though I still have a coax running to my TV tuner to watch other network shows that I can't record with my 622.
I'm interested in the moving concept, no idea how it works. Would make my TV watching so much easier, and enjoyable. I'd really like to know why Austin hasn't done anything about their HD locals. I can't even pick them up with my OTA rig. Are there even HD channels out of Austin?
