If I run the AVI through VirtualDub, then ImageJ will read the entire AVI.
Virtual Dub says something is wrong with the AVI indexing in the AVI's written from ImageJ. It's not a RAM limitation.
I can get it to work, it's just an extra hassle to have to go through virtualDub everytime I want to open a large AVI.

This is a known limitation/bug of ImageJ 1.x's AVI Writer [1].
Did you try exporting your data using the Bio-Formats Exporter [2] plugin?
Off the top of my head, I do not know whether it supports proper exporting of >2GB AVI files, but it is worth a shot.
Regards,
Curtis
P.S. to Michael Cammer: problems with ND2 and CZI are unrelated; those formats are not AVI-based.
