I have a Mits ws-65819. (65") The specs are: 480i source scanning rate: upconverted to 480p 480p sources scanning rate: 480p HDTV scanning rate: 1080i Comb filter: Motion-Adaptive 480-line 3d y/c. I have about $300 for a DVD player. Do I need the RP91 or can I use the RP82? Is the cp-72 similar to either one?
