Thank you guys for the advise, it seems that I found a partial solution: I used my Belkin power conditioner and the hum is not that loud. It is still there but not as much, I could not hear it while sitting on the sofa and watching a movie, but I could hear it if I mute RC-1070, or if I am changing DVDs. HDTV works fine through Belkin line conditioner. What I did is run the coaxial cable from the cable splitter to Belkin Cable In jack and then another coaxial cable from Belkin Cable out jack to the TV. I will try Jack's advice (sorry, got the meaning of your post but after I posted mine), through a simple video cable and not through s-video cable I now use from the DVD player to the TV set.
