Hi,
Thanks for the detailed description. Because I was able to clearly understand you, I have succesfully resolved the edge-case where *.bc! files are incorrectly being picked up as video files. Since the prefix is a valid video (and it was not foreseen users would try to catalog folders in a changing state), video files were being selected incorrectly based on a loose regex which has now been updated. You should be able to see change in the next version of Jav-It (Sometime this week or next). I suspect that with this change, all the extra files that are generated shold now go away. (^_^);
As for your missing titles, that one I am still unsure about. However, because of the strange edge-case you were trying to do, maybe that was the cause of it. There is a likely chance that by igoring *bc! files, a lot of this strangeness will go away.
