Does anyone else w/ the new DirecTV HD Tivo Unit have problems getting the MLB Extra Innings channels? I get all of my other channels fine, and the MLB Extra Innings Channels show up fine on my other receivers (non-TiVo)--just not on the TiVo unit. I have called DirecTV three times on this and they are clueless. Last night, a technician was able to resend a signal that got it working, but today it's back to the same problems. All that shows up on the screen is the DTV logo. Anyone else had this experience?
