I was talking to a friend who has been in the encoding scene for a bit and he said this issue doesnt sound like a bitrate problem, but perhaps a framerate problem.... I'm sure it's fixable. Just have to trial and error it.
I'm with your friend -- it feels like a framerate problem to me. Let's review.
The original video stuttering problem was seen when directly importing the mkv file into TMPGenc Xpress and not
changing the input framerate. I have seen this myself and it's very ugly. The motion becomes jerky and it is constant and unbearable.
Chris discovered the magic technique of changing the input framerate to 24 fps when it is detected as 23.976. This makes the constant jerking go away, but seems to add the "hiccup" every 41 seconds. In every test render that I've done so far, I get the hiccup. It's much better, even watchable, but no good for archiving.
BTW, the playback testing I've been doing is in WMP11 since the output is a wmv. The hiccup is the same in WMPC -- 41 secs -- so this has nothing to do with the Xbox 360.
Finally, a quick rundown of my setup: Vista Home Premium, TMPGenc Xpress 220.127.116.11 (full retail), Haali Media Splitter, ffdshow-tryout 4a. I do not
have CoreAVC installed (yet), nor AC3Filter.
