I have installed a Dreamcast (I know, old school) and plugged it in to the AV1 jacks. It works, but the video has wavy lines in it, and the audio has a slight buzzing noise.

I plugged the dreamcast into my TV in my house and it works fine, no issues with the video or audio..

anyone have any ideas as to what could be causing it? I have tried playing with the settings but nothing has worked. I also attempted to securely seat the connectors, no change. I also have subwoofers, could it be the EMI from the AV cables going back to my amp? (I'll test this and post if this works).

Thanks

its the power inverter that your using.. plug the dreamcast (what the hell man?) in using power from the house and see if u still get the lines
