ok, the reason i asked is because some 3d players will work with your 5.1 receiver and some wont.. so you can rule out sony, pioneer, philips, etc.
you have one choice a
samsung c6900 .. it will work fine with your current receiver.. its the only 3d player to my knowledge that has multi channel analogue outs, which you require to go with your non hdmi enabled receiver...
Not neccessarily, max... Really depends on what connections are available on the OPs receiver/surround system.
Since the OPs receiver/surround system may/may not have multi-channel analogue inputs, but it will more than likely have optical inputs, so could be used with some/most of the Sony,Pioneer, etc, 3D players, the op just won't get HD audio.
Ideally we need to know what make/model the receiver is or what connections it has available....
