Why Won't The Dvd Load? Dvd Player Turns On. The Disc Tray Opens And Accepts Dvd
The TV displays the message "loading". A humming sound that changes pitch can be heard. After several minuates the DVD is ejected. The DVDs, I tried two different ones are rented from RED BOX that played on my lap top.
