I currently have Time Warner triple bundle, want to dump cable part and get Dish Hopper and Joey for 4 TV's, any issue with Dish installer making the switch to install Hopper. I ask as I'm not sure if disconnecting TWC Cable boxes would effect existing TWC Internet and phone. I could switch Internet and phone to AT & T but want to keep it simple. Would appreciate any insight, don't want to order Dish until I know what's going to be effected.
