Comment (by markfilipak):

 Continuing my exploration, I have news.

 I transcoded the video & audio. Then I extracted the subs separately. Then
 I merged them.

 The result DOES NOT exhibit the problem. The subs lead the audio by 1:14,
 but otherwise, the merged version works correctly.

 I hope this info helps. If you want any of the logs, I saved them. The
 command lines follow.

 Step 1: Transcode 2001av.MKV.
 ffmpeg -report -ss 2:57 -analyzeduration 5000000000 -probesize 5000000000
 -i "G:\BDMV\STREAM\00000.m2ts" -filter_complex
 "telecine=pattern=5,split[A][B],[A]select='not(eq(mod((n+1)\,5)\,3))'[C],[B]select='eq(mod((n+1)\,5)\,3)',pp=linblenddeint[D],[C][D]interleave"
 -map 0 -codec:v libx264 -crf 20 -codec:a copy -codec:a:1 pcm_s16be -sn -dn
 "2001av.MKV"

 Step 2: Extract subtitles to 2001s.MKV.
 ffmpeg -report -ss 2:57 -analyzeduration 5000000000 -probesize 5000000000
 -i "G:\BDMV\STREAM\00000.m2ts" -map 0 -vn -an -codec:s copy -dn
 "2001s.MKV"

 Step 3: Merge 2001s.MKV & 2001av.MKV to 2001.MKV.
 ffmpeg -report -analyzeduration 5000000000 -probesize 5000000000 -i
 2001av.MKV -i 2001s.MKV -map 0 -codec:v copy -codec:a copy -map 1:s
 -codec:s copy 2001.2.MKV
