Found a few more - check in the YouTube comments.

You know, some maps are actually repeated - I know a few which appear in two (even three) compilations, but usually in different spots. One of these maps, for example, is E1M3 in one pack, but is E1M8 in another.

And a funny thing - if a map has some custom episode name thingie (like Hades's House), it gets carried over into the compilation. That's why in ep5a you get that custom blue text for episode selection (because E2M2 is Part 2 of Hades's thing).
