My installer set up my 52.0 remote to use the TV volume instead of my Yamaha AVR. I did that last night which was super-easy. It had my RX-600 series receiver in its database and after the remote got configured, I changed the Remote Setting so the volume & power buttons controlled the AUX instead of the TV. Once I use the Harmony to "Watch Dish" I can switch over to use the 52.0 remote for 99% of watching activities.
I had to go to work after my install was finished, but it took so long that my son had come home from high school and he settled in watching his shows. So the Hopper wasn't idle until later that night. By the morning after the install, all the channel logos were in the EPG. Most (but not all) of the shows that recorded in the PTAT folder had the program graphics and not the Network Logo. Today I look and it seems to be the new shows that haven't got the program graphics. But I guess it depends on Gracenote since there is a blurb on some screens that the information comes from them.
