I have vertical lines that are moving horizontaly accross my screen when I feed either my digital cable or my DSS threough my 3000. I have tried both composite and s-video ( Monstercable MSV-2000 and 1000) into my JVC. I have tried both component and svideo out to my tv. I have tried it on two different TV's, and it still remains. If I connect the digital cable or DS directly to the TV, it goes away. If I play the demo tape it is not there. So it has to be in the input. Anyone else have this problem? Any suggestions?
