My Craig DVD player is attached to a Samsung VHS player. I view only DVD's & VHS's on my Insignia TV. The DVD player works, but nothing appears on the tv screen. I use L1 to play VHS's with no problem. Also, everything worked ok, before I attached a ClearTV antenna, but I ditched it when I lost DVD transmission. Is it possible the I lost channel 3 (I don't have cable), but if I did, would I still be able to play the VHS tapes?
