I recently changed from cable to Directv HD. I hooked up my series 2 Tivo unit to my satellite receiver and everything works great except for my local channels. When I try to change to a local channel using the Tivo remote it tells me "Channel not available", however when I change to the same channel using the satellite remote it works just fine. When I open the guide in Tivo it shows duplicates of all of my local channels. For instance, it shows 4 KDFW and 4 KDFWDT, 5 KXAS and 5 KXASDT. I assumed those are local HD channels I'm receving so I tried disabling the "DT" channels in Tivo's set up, but that didn't work either. Any ideas?
