I am having a very hard time determining how to hook up a DVD player to this Polaroid TLA 04011C. I have a Comcast HDMI DVR cable box hooked up to the TV and that's working fine. I am trying to hook up a coaxial cable between the DVD player and the Polaroid and I have 9 input source options: TV (Cable/Air), Video 01 (Side), Video 02 (Rear), Video 03 (S-Video), Video 04 (YPbPr1), Video 05 (YPbPr2), Video 06 (HDMI1), Video 07 (HDMI2), and Computer (VGA). I have tried essentially ever conceivable combination of source inputs with the coaxial cable inserted into the corresponding connection on the back of the Polaroid. I would very much appreciate any assistance.
