Codec for old Matrox MJpeg hardware compression?

Archived from groups: rec.video.desktop,rec.video.production (More info?)

Several years ago I had an old Rainbow Runner card with the Matrox hardware
MJPEG and when I replaced it, the PICVideo software codec I installed read
my old files fine. And you can try it out free and see if it works for you
before you buy it.

I never found any codec which could handle many of the MJPEG files I
had lying around, apparently because they were cropped at the edges
(trying to save disk space by removing the pixels you'd never see on a
TV) so the width wasn't a multiple of 16... I could read some other
MJPEG files where the width was a multiple of 16, but the cropped ones
all came out skewed horizotnally.
