Pioneer Elite DVC 36 DVD versus DV 37?

Yes, 3-2 pulldown is important. As I understand it, a DVD player that has this feature most accurately recreates a film-like progressive image.

I have that Pioneer literature. The way I understood it was that the NTSC standard is to break up each film frame into 3 and then 2 interlaced images. A player with true 3-2 pulldown capability will accurately replicate each film frame from the NTSC encoded disc. I could be wrong, but that's what I read.
