Okay here is an update.
When I use the global "create videos" feature, it appears to be working as designed. It does not appear to be skipping tables at all. I was "ASSuming" it would go through the tables in alphabetical order, but this does not seem to be the case. It seems to go after EM tables and early 80's tables first, and then it moves onto to DMD tables towards the end.
Anyone know what the order is that the PinballX recorder follows when using the global "create videos" function? I have not tested enough yet to see if its looking at year or something else. Buts its definitely not alphabetical order.
Have not looked at DBM yet.
