Direct TV and digital hum problems


Hello,
I hooked up a digital 5.1 reciever for a non audio bud tonight I donated to him. When I hooked up his Sat box via Roslink I got a high pitch faint but annoying hum thry speakers. I figured I would try dig coax and same result. I lastly hooked it up for Pro logic and no hum but its not digital as I had hoped to give him.
I lifted the ground, checked the ground at the junction amp in basement and all settings were verified.
I am by no means new at this, I have over $50k in my home theater and have done surround for over 15yrs all along being a DIY installer (I am also the nerd everyone calls for help.........and am pretty good at it too :)
My point is that I have tons of experience and just cant figure this out, hope some ideas come my way..........thanks all!

That phone line is a awesonme idea, if it isnt that then I am stumped. I will try that when I get back over to his house this weekend. Thanks for the idea!
The phone line didnt work, I wonder if its the way he has it stacked, on top of guitar amps and such (everything is in one big stack) could that be an issue?
He isnt an audio guy so I cant blame him but I would like to give my friend a little better sound. Thanks
