Advertisements After going through the guided setup (I followed the instructions after seeing a message on my 810H that a channel lineup change required an update.) my Pioneer 810H unit can no longer change the channels on my Direct TV satellite unit. I have had my 810H since Dec. 04 and have been using it fine with the Serial cable connection. Until I update the 810H (software version now says 7.2.0-tak-01-2-275. I'm wondering if anyone else has this new version and if they are seeing the same problems. I went through the steps of powering off the Direct TV box and this did not fix the issue. Could anyone help me out in discovering what to do next? None of my shows are recording as a result of this new software version. UPDATE: After speaking with someone from Tivo beta support, they informed me that they are slowly rolling out the 7.2 software to users and I was one of them. I'm not a beta tester however. I have a DirecTV HTL-HD receiver. Apparently, DirecTV has change the protocols they use to send data over the serial connection. With the new Tivo 7.2 software, Tivo is using this new or change protocol as well. This makes some sense, however it's frustrating since I know I can't be the only person out there with a Pioneer 810S-H and a DirecTV HTL-HD satellite receiver. Now I just need to yell at DirecTV and Tivo to see if they can make any changes before Tivo fully releases the 7.2 software. I was also able to get channel changing to work after messing with the IR cable. I had to stick it pretty far away from the IR sensor on the DirecTV HTL-HD receiver.
