OK so here is the situation.  I recently had to rebuild my NAS from a disk failure, I put it all together in the same way, files in the same places, SQL database all the same with the same passwords, etc.  It can access the files, it can play them all, but for whatever reason on both Windows, Android, and Linux versions of Kodi whenever I load into a TV Show it just goes to a black screen showing the background and sits there for up to ten minutes, usually "only" five.  I thought it was maybe some strange thing where it couldn't see the thumbnails correctly (which are hosted on a remote share) or that I had some passwords wrong but I've now gone to the extreme of sitting with two NAS, one configured with an exact restore of my old one, and one with the new setup side by side and gone through every single line of code and there are no differences.  Is there anyway I can see a log of what is happening in Kodi that's causing this massive pause?

Even when a show has been loaded this way you can then play an episode, works fine but when you hit stop and it would normally just jump back to the main screen again with the five minute pause....

I really have to return this second NAS to the mate I borrowed it off and clear all these drives back to normal but I'm paranoid I'm show how missing something!  Anyone got any suggestions?

OK so I worked it out.... My Kodi DB got corrupted on the import.  It looked fine but but some of the data had been made garbage, oddly it was so close to mostly working that Kodi seemed to be fine, except when it was loading a bunch of entries at once like it does for the full TV shows listings.  Would still be good to know if there was a way to see these errors in the logs not just replace everything and waste hours.

It's useless to continue with a corrupted database, so old log files are obsolete too. Best is to start from scratch, and enable debugging by default via the loglevel tag in the advancedsettings.xml file.
Although you are using a NAS, it is still not a backup device by itself. You could consider creating a proper MySQL dump every so often, and/or do a Video Library Export so metadata is stored in .nfo files.
