I bet the problem is -- AVI container not signaling the
aspect ratio properly. It's been a problem for broken
application all along. It's a pity if Adobe Premiere
happens to be among a broken bunch.
The only possible workaround that I know of is to
do what is done for AVI type 1 DV, but it'll be more
trouble than it is worth. IMHO.
