We are - and yes it is rotten quality (tape was on the verge of
causing the VCR to mistrack). The original 4:2:2 uncompressed data
was better but after the mjpeg-A downconvert (using mjpegtools ;))
the quality took another drop.

The specific problem I had in mind was the blocks/squares that are
visible in the blue areas of the sky - those blocks are not visible
in the Bitvice encoded .m2v file.
HOWEVER - the new and improved mpeg2enc is vastly better than it was
2 days ago!
I'll move on to better data now.

I think that's the general direction that MJPEG support's headed
as cards cease to work or be supported...

For inexpensive nothing beats a Canopus ADVC-110 (the -300 is good
but I've come to the conclusion it's not worth the extra money over
the 110). Use dvgrab/kino to do the acquisition and editing.
the 'j' in mjpegtools is a bit out of place perhaps today :)
