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.

2) I just repeated my earlier stated procedures, this time using v.1.4.8 as you requested. I'm pleased to report that the previous problem appears to have been overcome with this version. IMPORTANT - Your website now shows a 672 byte file "dscombo.svq", pertinent to BD+ disc-ripping. Information is not very clear: 1) Does this 672 byte file PRESENTLY include any generic or disc-specific information/keys? 2) If so, how is it made available/accessed/viewable? If not, what is its purpose? Please advise... Last edited by setarip_old; 9th October 2009 at 04:19. Reason: Eliminate erroneous statement |

You download it into "SVQ directory" (set in preferences) and these titles start work. |

@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
The way you/your company has chosen to deal with us, the users/beta testers regarding the BD+ function seems grossly unfair: On one hand, although you appear to have it, you are NOT providing the generic key for earlier releases to us. On the other hand, rather than providing us with the tool that would allow us to create our own "SVQ" file information from "dump files" created from OUR purchased BluRay discs, you are compelling us to to provide you/your company with our information. Please justify your thinking regarding this. As a sign of good faith, I'd propose that you/your company make the generic key for prior releases available to us, the users/beta testers. |

On the other hand disc-specific SVQs are like volume keys - they unlock a single disc but they contain no information about how they were created. So AACS/BD+ folks know that we have a key and know how to use it but they do not know which specific key out of 65529 non-revoked keys do we have. That allows us to enable BD+ for everyone and still work on improving our BD+ implementation. Releasing generic SVQ now will only burn a resource that is very hard to come by. |

On the other hand the current absence of a generic SVQ is a temporary thing. Generic SVQ will be released sooner or later and this nuisance will go away. |
