i have a silo 32 inch hdtv, i also have a goldstar dvd/vhs combo. its hooked up to the hdtv and the dvd part plays wonderful, but the vhs part does not. it plays but the picture is distorted and shaky, like it needs tracking or something.how can i fix it so that the vhs part plays ok?there is no tracking button on the dvd/vhs combo. thanks for all answers.
