Joining MP4 - synch issues

Hi!

I am having synch issues when trying to join MP4's:

The film is Fellowship of the Ring - 2 DVD, compressed to AVC +2xAAC ( +2xttxt +chapters), the seperate 1st and 2nd parts are fine. After muxing (with MP4Box), A/V synch breaks at the end of the fist and beginning of the second part.

YAMB/MP4Box tells the video in part 1 is 1:41:18:840 long, and the two audio streams are 1:41:17:909 - difference could be the source of the problem..

Question is: is it a bug in MP4Box, or is it a bug in the user?

EDIT: just checked the ttxt subtitles, they have the same problems as well..
