Audio drift in blu-ray project

Greetings! I'm having trouble finding a solution to this issue, though i see people complain about it in quite a few threads around the net.

I'm in the process of authoring a Blu-ray project. Footage was shot on the Panasonic AF-100 in 24fps 1080p. Footage is edited in FCPX in a 23.98 timeline, exported as a self contained. Self contained is taken to AME, exported using

H.264 Blu-Ray (Legacy)
MainConcept H.264 video
All settings automatic
Profile is Main
Level is 4.1
Render at maximum depth
VBR, 2 Pass
target Mbps 15
Max Mbps 20
Keyframe is unchecked
Max render quality is checked
Frame blending is unchecked

I tried a few tests before going with these settings, and at first it seemed like my exports were good. I burned out test discs and tried on a few different player models, all seemed fine. I did notice my audio was slightly longer than the video in the sequence for my test builds.

As I moved on to compressing a longer video (114min) I realized the audio was sliding out of sync badly. Comparing the exported video to my source self-contained, it's shorter by a few seconds while the audio file is still the same length as the source.

The best I can figure is the 23.98 footage is being converted to 23.976 and dropping a few frames, although I keep seeing people say 23.98 and 23.976 are the same thing. Any idea how to deal with this problem?

OK, so is there a solution to the problem or no?
