Hello everybody, this is my first post. I just bought the Sony DVD/VHS combo SLVD550P. I'm using the good old composite yellow output for my picture, not the Y-R-B outputs. When i'm plugging the player directly into the composite input of the tv set, no problem, but when i'm connecting it throught my Denon AV receiver, the picture is all wavy, like the one you got when you put a macrovision protected dvd through a vcr. But the thing is, the problem do not come from the Denon receiver since i can plug any other dvd player i can think of without any problem. So could it be that this particular Sony model is faulty or could it be possible that this is all about an hardware incompatibility between the Denon and the Sony. A very important point i forgot to mention, DVDs that i know for sure they are not protected by Macrovision plays fine with the Sony, only commercials movies or other macrovision protected dvds are affected. Thank you very much for any help. I hope i'm falling into the guidelines of this forum. André.
