Also, I am not sure how the concept of 'album' that you mention would translate to video files.
What is the format of your video files? What sort of metadata do they contain that MusicBee could make use of?
The equivalent of the album field for audio is the "series name" field for videos.
Disclaimer: personally I only use MusicBee for audio, so I have no useful insights or opinions or how it can be uses for video.
Maybe sort by title?

I'm not that picky. Up to now, your solution sounds pretty good, honestly... 001 Title, 002 Title, etc. I like it. Simple and straightforward. The only tweak I had to go do was change the sorting criteria via "Sort by > Define custom sorting" and then having MB sort video tracks in the following order: Album Artist / Album / Title. I'm not sure how they were sorted at first, but it looked pretty random to me. And it changed every time I refreshed MB, which is strange. But now it works.
It did the trick. Thanks for your help.
