Compared are the Original Version (1989) and the New Version on the "Finding Nemo" DVD (2003).

For those who don't know this short movie: some toys on a shelf are having a party with music and swimming pool. A bit apart is a solitary snowman, he's trapped in a snow globe. He attempts anything one can imagine to join the party.

Unfortunately the humor doesn't seem to be "political correct" nowadays. That's why the size of "Miami Girl's" and the mermaid's breasts are drastically reduced on the "Finding Nemo" DVD.
Maybe Pixar was too anxious about possible complaints from parents due to the presentation of the women.
I feel blue about the fact that Pixar "violates" the own artwork and modifies the movie for its rerelease.
Original Version from 1989 - Version on the "Finding Nemo" DVD = 13 sec

The Original Version is 13 sec longer (03:49 min in total), but that is only because of the extended credits.

Quality
The quality of the iamges is really amazing and much better than it was in the Old Version: the brightness, the contrast and the resolution have been modified. Furthermore all surfaces look much better. Another difference is the missing Pixar logo in the right top corner in the New Version, which won't be missed by anybody, I guess.
