Again, not all Sony LCD displays have 120Hz frame rates, but for those=20
that do, yes (now that I'm reading this again), the 120Hz Motionflow=20

Motionflow, 3:2 pulldown is still included.

24p True Cinema (24p Input Capability)

Many movies are filmed at 24 frames per second (fps) and prime time TV=20
programs are recorded at 24p.  Seizing on an op****tunity, some studios=20

s****ts with a greater sense of realism than ever before.

I have both an old 480i and 480p DVD players.  I've tried both with the=20
same source material and they both look virtually identical.  I believe=20
the Sony display auto-senses the i or p material (depending on which=20

a difference all else being the same.

I use HDMI for everything that accepts it, and component where it's not.

I don't think I can based on how I understand the menus - 24/30fps auto=20
or 30fps only.
