Chapter Markers shift after build in Encore when using PP dynamic lnk

Question

When I create a sequence complete with perfectly placed chapter markers in Premiere Pro CS6 and send it to Encore via the dynamic link everything appears fine (it even simulates perfectly) until I build a DVD in Encore. After the build in Encore most of the chapter markers have shifted and are no longer perfectly placed. It's as if Encore encodes the video without regard to the chapter marker information and then adds them onto the already encoded video where they have limitations on which GOP frames they can appear. Shouldn't Encore take the chapter markers into account while encoding the video? The way around this I found is to export the sequence from PP and then import the video into Encore. All is well if I do it this way but I like the advantages of dynamic link. Encore just doesn't seem to respect the chapter marker information. Am I missing something or is this just a flaw in Encore?

Good questions.
Yes my source clips codec is motion jpeg at 29.97fps.
If I just focus on the second chapter marker in my test sequence (given the automatic first chapter marker is at 0 sec.) it is at 1:01 in the timeline which is off the GOP boundary of 15 frames. When I build the timeline this marker moves 1 frame back to 1 sec., a GOP boundary. Doesn't sound like a big deal but that puts the marker into the previous clip on my time line which causes the automatic thumbnail in my menu to be wrong and there's a little flicker when you jump to this chapter on DVD playback as it plays this one odd frame.
I guess I am transcoding during the build (am I not supposed to?) but I have since tried your idea of trying "transcode now" before the build. It sounded promising. While looking at my second chapter marker in the timeline I clicked transcode now and watched the marker jump back 1 frame. Cool, but I'd rather it didn't do that.
You are right I don't need a menu to examine this. It's just that the thumbnails changing in my menu after a build were the firts indication to me that something was going wrong. Again if I import a file that's already transcoded  to En this isn't an issue.
It just looks like En doesn't respect chapter marker locations through the dynamic link to Pr and it should. It rather transcodes first and then adds in the chapter markers as close as it can to their original locations. It's possible I am missing something in my workflow but it at least sounds like you understand what I am experiencing.
Can you try modifying your test by creating a couple of 1-sec clips in Pr sequence with a chapter marker between them (so your first one is at 1:01) and then see if the same thing happens to your first chapter marker?
