Yeah AVI is a container. It can be MPEG-2 or MPEG-4 video (e.g. DIVX or XVID) too. It depends on how the video is constructed. for MPEG-2 with only I-frame (there are I, B and P frame used in MPEG-2), Premiere can edit it without hiccups because I-frame only MPEG is frame accurate.
I seem to remember Premiere 2.0 also handle MPEG editing okay. CS3 is a mess. Audio got out of sync during any drop out in MPEG2 file. sometimes it also goes into a non-stop audio conforming and indexing loop. One way to handle is to create a "proxy" version of the MPEG file you have to an AVI. Then edit that AVI file. Once done before exporting, rename that AVI file so Premiere will ask where is that file. Point it back to the MPEG file. In that case you can export a better quality without editing that MPEG file directly.

A while back I worked at church with avi's some containing mpeg1 and others containing a four CC codec something like YU50 (I forget exactly but it was close to that designation). Because of your comment about CS3, could it be that Premiere versions prior to CS3 have some issues with mepg2 that got corrected?

Every single frame from the video is a complete frame. MPEG-2 deploys inter-frame compression which takes Premiere extra effort to re-construct a single frame when you scrub the timeline. Therefore, Premiere is much happier editing AVI files instead of MPEG. CS3 can handle editing MPEG-2 as it indexes the file during import. MPEG-2 is a delivery format. It's not ideal to edit MPEG-2. However, for HDV, it's unavoidable to edit MPEG-2 unless you have a third party HDV codec such as Edius, Cineform or Matrox.
