The video does need re-encoding as it has letterboxed content and the black bars aren't in the source (i.e. it's not 1080 pixels high).
BDRB re-encoded the video at 23.976 an re-encoded the EC3 audio without other amendment (i.e. equivalent to 24fps) - meaning that the lip-sync drifted throughout and was was off by something like 1/2 second at the end.

So instead, I'm having to try avidemux to re-encode both whilst retaining the 24fps timing.
When BD-RB converts rates, it should also adjust the audio. Can you look at the AVS for audio and see if it does?
