tsMuxeR giving "Reading buffer overflow" error at 47.4%.

[hbenthow]

I'm using tsMuxeR to mux an m2ts file from the STREAM folder of a Blu-ray folder I authored with BD-Rebuilder into another Blu-ray folder. I'm doing this because BD-Rebuilder gives me no control over the subtitles. I BD-Rebuilder to author the Blu-ray from non-Blu-ray compliant files, then use tsMuxeR to create the final Blu-ray with the subtitle size, offset, etc, adjusted to my liking. I've already done with multiple times, without a hitch.

But now, with my latest Blu-ray project, tsMuxeR always stops at 47.4% and gives the following error:

Reading buffer overflow. Possible container streams are not syncronized. Please, verify stream fps

I've never had this problem before, and have no idea how to fix it.
