I sent a shared Dropbox folder with svq@makemkv.com with the file dump inside.

SVQ updated.

The first disc ended up working after your update but now having issue with the second disc.
The updated SVQ file worked for Disc 1 after you updated it, but not for disc 2 and 3. I dumped the Dump files in the same dropbox folder. I appreciate the fast response and the effort.

Disc 2

I'm having the same issue. Disc 1 works, 2 and 3 do not.
