I bought a new Seagate 6TB desktop external hard drive. My Hopper 3 will not see it. Tried every port and rebooted. It works fine with my laptop.

I have two 522s and 3 TVs. Can i set the first 522 TV1 output to channel 3 and TV2 output to channel 60 Second 522 TV1 output to channel 4 and TV2 output to 61. Can I combine all outputs into one cable and then split that cable and send to all TVs thus allowing me to access all four channels...
