I got my PS3 and used the composite cords first hooked up to video 1 but got the humming noise with lines through the screen so I bought component cords and still get the noise. My DVR is hooked up to component 1 while the PS3 is hooked up to component 2. If I unhook the audio cable only red and white from the back of the DVR while the PS3 is on no humming but if the audio on the DVR is hooked up as well as the PS3 I get the humming. Anybody having this problem and if so did you get it fixed. My TV is not HDMI compatible so please don't bring that up.
