WoW remux, time offset

[Spearfish25]

Hey all,

Trying to remux the 4K video from War of the Words with the older DTS 5.1 audio track. Trouble is the new 4K stream has a bunch of intro video that means I need about 2min 40 second delay on the older 5.1 DTS audio stream. Struggling to figure out how to get the right delay.

1) has anyone done this and know the right delay to add to the 5.1 track? I'm using MKVToolNIK and can add a delay easily...just can't nail the right amount.
or... 2) Which software will allow me to analyze my MKV file and edit the audio tracks to find the offset? I know premiere pro doesn't support MKV files.

OK, the answer is 160,577 milliseconds offset.
