Comment (by petere):

 Yes I tested with analyzeduration and it took a long time but still did
 not get the correct duration or bitrate.  Upon further investigation it
 looks like the timestamps reset in vob 5 so the duration is correct in
 vobs 1, 2, 3, and 4 but 5 starts at 0 again.  So if ffmpeg reads the
 timestamps from the end of the file they will be less than the start and
 the duration and bitrate will be incorrect.

 I tried using the separate vobs and the concat: input but this does not
 use analyzeduration so it does not find all the subtitles when I use
 filter complex to burn subtitles.
