UPDATE2:
Thank you for sending all requested information - SVQ file for Avatar is available, there is no need to send any files.
UPDATE1:
Modifications to handle new BD+ are in final stage; the new program version should be available approximately in a week.
Everyone, who have sent a tgz dump file to svq@makemkv.com - thank you, you have made the coming update happen. However, more information is needed. The new BD+ code uses a radically new approach and certain file that is required for proper SVQ generation is not packaged into TGZ by current version of MakeMKV. If you have sent the tgz dump to svq@makemkv.com, please send additional file from the disc to the same address. The file in question is 77001.jar and can be found in BDMV/JAR folder on the disc. If you can't access any files on the disc, you can create raw disc backup ( by selecting "backup" from File menu and un-checking "decrypt video files" in backup dialog ) and copy the file from there.
When sending this file to svq@makemkv.com also mention the filename of original tgz dump file, for example
There is no need to send a TGZ dump second time.77001.jar for dump_Avatar_27ABDD19AE93BC8A.tgz
Once again, Thank you for your patience.
