Now I know "The New Batman Adventures" is a spin-off of Batman: The Animated Series, but regardless, I would like to add the entire series of The New Batman Adventures to my Batman: The Animated Series set, under season 4. I would like to do this as I want to make use of the volume 4 cover for the BAS set, and the original volume 4 DVD is the series of The New Batman Adventures. And because I don't want to use a custom cover for The New Batman Adventures as it was never officially released by itself.

How can I go about doing this?

Use a program like Media companion, xMM2, or EmberMM to scrape the episodes and create .NFOs.
Then add the files to the same folder as season 4 and edit the .NFOs accordingly.

That did it. Thanks!
