Okay, maybe someone else can watch The Three Caballeros on its original VHS or Laserdisc release(s) a couple dozen times to verify this for me (and confirm that I am in fact NOT crazy in this instance), but I thought that there was a frame that WAS edited out on the DVDs.

Specifically, it was during the Flying Gauchito sequence and when the title character and his mount fly through the frame in this one instance, there was a smoking man and his horse, and when the flythru happens, the HORSE is the one smoking. I have NOT seen it on either DVD release, which is quite worrying that they didn't do a proper Walt Disney Treasures release for this movie and the other 'package features" because we will very likely never get a proper, nice-looking release for these amazing movies ever again.
