I have a Panasonic plasma tv with an s-video connection and a scart connection. I have a dvd/surround system with 1 x scart connection, a vhs video recorder with 1 x scart connection and a satellite box with 2 x scart connections. Note that the plasma does not have an ariel connection. How do I connect the lot together? (I have got the plasma working with the sky box, but when i plug the s-video lead into the plasma for the dvd to work the screen goes blank!!)
