Thanks for the suggestion, Jelio. I understand that all the version history for the six books can be really, really confusing - heck, even I'm slightly confused by it all! Anyway, to summarize the version details, here goes:
Book 1: DVD v2.0 AVI v2.0
Book 2: DVD v2.0 AVI v1.0
Book 3: DVD v2.0 AVI v2.0
Book 4: DVD v1.0 AVI v1.0
Book 5: DVD v2.0 AVI v1.0
Book 6: DVD v1.0 AVI v1.0
This is actually a simplification, since Books I and II are actually in their third versions. Also, I have no plans of making a v2 of Book VI. So a simpler way might be:
Book 1: DVD Final version AVI Final version
Book 2: DVD Final version AVI v1.0
Book 3: DVD Final version AVI Final version
Book 4: DVD v1.0 AVI v1.0
Book 5: DVD Final version AVI v1.0
Book 6: DVD Final version AVI Final version
Adding this to the fanedit pages would indeed be a good idea, I'll PM boon about it. Anyway, the gist is, the DVDs for Books I, II, III, V and VI are the most up-to-date, and, as far as I know, the final versions. I'm planning to create an updated version of Book IV, but the changes will likely be minor - mostly it's just to make the opening and ending sequences match with the updated design.
Hope this clears it all up somewhat, and I'm glad you enjoy the edits!
