SpongeBob SquarePants: Complete 2nd Season (Disc 3), and SpongeBob SquarePants: Christmas
Both are Region 1, NTSC DVDs

One issue with the "Season 2" DVD is that most of the episodes have incorrect color composition. For Example, in the episode "Procrastination", on the "Christmas" DVD, SpongeBob looks normal. On the "Season 2" DVD, SpongeBob looks rather pale and doesn't accurately depict how it was originally aired, unlike the "Christmas" DVD.

Another issue here, which I would like to talk about, is the encoding.
I am going to use "Avidemux" and the raw VOB files from the discs to demonstrate this scenario.
All of the frames on the "Season 2" DVD are marked as "TFF" or "Top Field First", which is to be expected from a DVD source.
However, on "Christmas" DVD, some frames are "TFF", most frames are "FRM" which is just a progressive frame, which doesn't seem normal to me.
Not only that, but the playback on the "Christmas" DVD is choppy compared to the "Season 2" DVD, whereas it is rather consistent.

I would rather preserve copies with the correct color composition so I could deinterlace them myself, but I can't work with such wonky scenarios. I will leave some images below so you guys can take a look at this phenomenon. If you can, please let me know what is going on, why is this happening, what can I do to counteract this, etc.? If you guys need me to upload anything else helpful, please let me know. Thanks!
