Thx. I tried with mplayer/mencoder and that works too, so I can convert
my wmv3 to an avi with the following properties:
ffmpeg version 0.4.9-pre1, build 4734, Copyright (c) 2000-2004 Fabrice
configuration: --enable-mp3lame --disable-strip
built on Dec 7 2004 11:33:45, gcc: 2.95.4 20011002 (Debian prerelease)
Input #0, avi, from 'arch2/x.avi':
Duration: 23:59:45.0, start: 0.000000, bitrate: 174 kb/s
Stream #0.0: Video: msmpeg4, 384x288, 1.00 fps
Stream #0.1: Audio: wmav2, 48000 Hz, stereo, 64 kb/s
I's now 1.9 GB, which neatly sidesteps big-file issues.

No, the ultimate goal is to use lavc/lavf to make one MJPEG per minute,
fps=1. (Kind of; its an in-house format very similar to MJPEG but dating
back to 1995, at that time MJPEG was far from standardized...) Since I
cant do it directly from the wmv3, I will start from that avi.
