I want to replace my old combi, but have had a bad experience with a newer Panasonic model using an hdmi cable between the combi and a Samsung television. I was getting pixilation of the picture through the link. What I want to know is if I have to use an hdmi cable or can I use a scart cable or some other kind of connective cable or do I HAVE to use the hdmi link? I am not a tech-savvy type so need the answer in simple easy to follow words. Thank you
