Wow Dude! i had the same problem, but with Ratatouilli.Blue.Ray.DTS.Remux.mkv only!
my setting was keyint=1:vqscale=1:vqmin=1 and this is the only movie in which i see some stuttering every once in a while. i changed keyint=25, it worked like a charm now, no stuttering. But, i see white noise in none-moving objects, comes up and goes with a sequence like a heart beat!! Am i making sense?! it is so hard to describe what i am seeing. but i am sure it is a white noise like things, and only on backgrounds where nothing is moving.
it is a gig network btw. and on a 52" 1080p LCD, so everything is noticeable
so could someone please explain what is keyint ? and what does the value 25 stands for? while at it, explaining vqscale and vqmin would be great
and what does the "transcode maximum buffer size" is for, and what effect does it have on quality if the value is changes from 400 to 600?? Because when i play mkv movies, the movie stops after couple of minutes as if i paused, i exit, then play it again, plays where it froze without problems!
