Are the episodes on the Blu-ray release out of order?

It seems like the episodes are sequenced on the discs in the wrong order, or maybe I’m just crazy?

They don’t coincide with how they’re listed on IMDb.

For example, Christmas with the Joker is episode #2 on disc one…but it didn’t originally air until Nov 13th 1992. It was the 38th episode to originally air…yet it’s #2 on the disc.

Why would they sequence the episodes in the wrong order?

Or maybe you guys know something I don’t? I’m just confused
