After database upgrade it won't recognize some movies even after reversing back to previous builds. The same movies will work just fine when scanned with new build of Kodi using fresh copy of official Kodi 17 with upgrade to #0602.

The old upgraded database flashes file name quickly during the scan and Kodi moves to the next file. I don't think this it's the naming. It works OK with official Kodi 17 even after upgrade to #0602.
If there is an issue with database upgrade since #0602 other people should see it shortly. Movies scanned by the previous version of Kodi are fine after upgrade. Only the ones scanned into #0602 are showing problem. If you change filename slightly on the existing movie and allow #0602 to re-scan it again it will produce this issue. One of them is Gringo.2018.1080p.BluRay.x264.DTS-HD.MA.5.1-FGT.mkv. Another is Tomb Raider and others but not all.

The upgrade of database was quick and without any errors.

I can't identify the first build. Everything worked until I upgraded today to #0602. After upgrade to #0602 some new movies scanned into #0602 were not recognized. They were still not recognized even if I reversed the upgrade to previously used April builds. I removed the source location and deleted associated records. After adding it back to #0602 I ended up with more unrecognized movies. The same thing happened with previously working build #0407. After database upgrade the #0407 is not scanning the movies that worked before the upgrade.

Can anybody check it. Just change something in the filename and rescan with #0602 or grater. It needs to be older database. Once you rename the filename and turn it into unrecognized press "I" for info.

Maybe it's just me or something on my system. It happened before

I'm confused as you seem to be saying (based on your posts) that this issue is present in #0602 (which included a db upgrade to v110), #0601 (old v109 db), and previous builds (presumably all based on v109, if they're older than #1214), while also claiming these builds are/were working. What build did you upgrade from, the one that was working? And if you go back to that version, does it now work, or not? If not, then I'd say it never worked, or something else has changed (outside of Kodi) which now causes the scan to not work.

If previous builds (prior to #0602) have this issue then the latest video database upgrade (from v109 to v110) has no bearing and we can safely rule that out.

Please try backing up your existing MyVideos109.db, enabling debug and then scanning your new movies into #0601 - do they now appear? If not then please post your #0601 debug log which includes the scan, and details of at least one missing movie.

Also, what filesystem are you using to store the movies - exFAT, NTFS, ext4?

I created a new movie, and #0603 scanned it without any issue (I'm using MySQL, which may or may not be important).
