Pink Floyd Pulse DVD

I now have the above and can play the 640 kbps and the 448 kbps versions. However the AV2 switches to Auto 3:2:1 in 448 but in 640 there is no auto option and no ability to play in 3:2:1. My DVD player is Pioneer 757.I
Is my DVD player simply too old or is it the AV2.

Thanks in advance.
