Did you test if your player handles correctly KVCD before to start making your own ?

Excuse me but I don't understand your answer : does your player handle KVCD correctly or not ? In other words, did you test this :

I used to see jerkiness also when I use CQ_VBR mode but nothing with CQ.
Your problem can also come from 23.97 movies that are 2:3 pulldown to 29.97.

You should give more details on what you do.

23.97 becomes 30? Not 29.97 ? For sure the problem is there !

When you tell "put in the video" you mean in what ? TMPGEnc ?

You must encode in MPEG2, and set in tmpgenc "23.97 internally 29.97" and the pulldown to "3:2 pulldown while play back".

Man ! Be more precise in your question :banghead:

Load where ? To do what ? What is the problem you encounter ?

My english is perhaps too poor but "load up" isn't even an expression I understand. So try to be a little more "schoolish" in your formulation please. We are far to be all natural english speakers here.

Thats is normal : TMPEGEnc set res. and fps according to the source each time you load a new one. You must do the things in that order : first load the source, then load the template.

But be carreful : if you have a source fps different than the one of the template (like here) you will have audio synch problem if you don't care.

So what are the TMPGEnc settings for avi's that are NTSC TV captures and are currently at 29.976 (or 30fps) to get to the correct frame rate to eliminate the jerky playback I am experiencing?
Thanks
