When they made the 97 SE they recomposited a LOT of the sfx shots, including shots that were otherwise untouched (this is how they got rid of the see-through snowspeeders).

Umm...actually, the transparent snowspeeders (and transparent ships in space, too) are still transparent in the SE, despite the fact the ILM claimed they fixed it through recompositing. Outright lie on their part, apparently. I'm not sure if any shots were fixed, but it's quite obvious that a great deal of them weren't...
