Not really. All it does is ensuring each frame will be displayed for the exact same duration, which is not possible with a 60hz set.

In other terms, this means the frame rate will jump from 20 to 30 all the time and 20fps is pretty damn low.

I love AMP, for me its like playing a game at 30fps or 60fps. You never want to go back to 30fps. I always hated the stuttering when the camera pans at 24hz. BBC documentaries are much more credible with AMP. Try it yourself.

On the soap opera effect, which is wrongly associated to low-budget film/TV.

Not everyone likes the effect and some complain that it ruins the cinematic look of home movies. For this reason, almost all manufactuers have built in an option to turn the feature off.

Really! That means my setup isn't perfect yet. I really thought this was a Samsung limitation as I get no frame dropped. As I said earlier, 60hz was not working well with AMP. Maybe I need to understand better how the PS3 sends the video feed. Is it 23.976hz?

I will make a new thread with what I learned and how to achieve proper HD playback at 23.976Hz with an HTPC.

It will be split in two. The first one will show (with setup screens) how to use MPC-HC, Autofrequency, Ffdshow, MadVR Lavfilter and Reclock or Ac3fitler to do AC3 reencoding over SPDIF. Right now, I have a very good setup with this and no complaints. Audio is perfectly synched and I got no dropped frames, no stutter.

The second will show how to do bitstreaming with the same software package.

Hopefully this will help some of you while staying focused on only one goal, automatic 24p with digital audio.

ah i finally understand what the op means. there's an option where i can enable the screen refresh to sync with the playback. if i have that enabled, then the picture becomes all 'stuttery.' there's another option in xmbc where i can force the video do display at the screens refresh rate while giving me options to resample audio or drop it or some other third option. for the most part, i leave both parts disabled and just watch the video and it seems ok. the audio syncs with the video as far as i can tell but i dont really consider my eyes to be super sensitive
