Either I'm a fool or my SMV file for part two of my Diddy Kong's Quest playthrough is corrupted. I would like to say that the the latter is the problem since while rewatching it while recording the file to an AVI, I noticed that a bunch of unnecessary things were being done over and over again.
But, after seeing myself go to an area I didn't bother recording until later on in the playthrough, I can only come to the conclusion that I messed up big time. I forgot to record over that part of the video again when doing my run and now I have to rewatch my first video, the beginning of my third one, and some of the later ones to avoid inconsistencies as much as possible.
What makes me angrier is that I made this mistake early on. If it were a mistake later on, it would be a lot easier to correct. I'm REALLY hoping I didn't do this with any other parts... If I did, I think I'm just gonna start all over at a later date, which is a huge pain since I went through some really hard levels and managed to finish 98% of the things to do in the game.
