MakeMKV v.1.4.6 hidden significant problem

@Mike Chen I used MakeMKV v.1.4.6 to rip the Extended Version movie-only of the recently released "Gladiator" BluRay. The size of the resultant MKV was 30,855,012KB. 1) I then used tsMuxeR v.1.10.6 to re-convert the movie-only into a BluRay "package" (Something I have now done without incident with more than 100 original BluRay discs). To my surprise, while the original disc and the MKV both played in perfect synch from the start to the finish of the movie, the re-converted BluRay "package" started out in synch and then ever so slowly (starting at about 1:09:00) drifts out of synch, until it's about 2 seconds out of synch by the end of the movie! 2) I resurrected MakeMKV v.1.4.5 and repeated the procedures exactly, using this slightly older version. The size of the resultant MKV was 30,855,375KB - 363Kb more than with v.1.4.6! After re-converting this MKV to a movie-only BluRay "package", I played it - and it stayed in perfect synchronization from start to finish! Hopefully Mike Chen etal will be able to resolve this aberrant behavior...

There was a major rewrite of MKV mux code in 1.4.6 so produced MKV files are more compatible with various players, that led to size difference. As for sync, I would need more data. Please PM me.

@Mike Chen I am feeling more unabsorbing than usual ;>} How is the user to know WHICH BD+ BluRay discs are already included in the (growing) SVQ file? I would like to know this information BEFORE I purchase any BD+ releases (presently only Fox releases, with the possible near term addition of Paramount releases). How can this be done?

Inequitable behavior re: SVQ data? 

@Mike Chen Thank you ;>}
