if i update an installation of max 4.5.7 / jitter 1.2.4 with the new max 4.6 installer, will it render the jitter installation invalid? (because it says max 4.6 requires jitter 1.6)?

I don't know if it will work. We have not tested the idea. I think in this case you will be better off just sticking with 4.5.7

I was investigating this issue quite a bit. My finding was that a fluent 

playback of a video is only possible when using the "direct to window" 

mode. it seems that this has nothing to do with the processing power of 

the computer. Also the suggested OpenGL methods do not work properly 

for me. Some time ago I was suggesting (and dreaming of) something like 

a "direct to OpenGL" method. But maybe thats just stupid.

What I did not try is using NTSC material (because I don't have some).

If you find a method of proper playback I would love to hear about it.

Sending from jit.qt.movie->jit.gl.texture or jit.gl.slab using 

colormode uyvy should be the smoothest solution.

You might also have problems if you have lots of UI elements. The 

performance of UI heavy interfaces can be improved by increasing the 

queuethrottle settings in the performance options window.

max/msp 4.6 + jitter 1.2.4 possible?
