I've upgraded to mjpegtools 1.6.1 now.

Figures. :-)  I've taken that patch out of my build.

You rule!  Thanks!

Sheesh!  What a convoluted mess!  As if I needed to be told that the DVD
standard was largely designed by non-technical Hollywood types. :-)

The original material was not interlaced, as far as I can tell.  I
interlaced it myself with the "-I 1" option to yuv2lav.

I'll send that in a separate letter.

Sure, but I warn you, it's a big hack -- I haven't figured out how to
work it nicely into the architecture, or to make it immune to
buffer-overrun attacks or anything.  The change itself is really easy; I
just replace the file-size-based method of inserting sequence-ends with
one based on frame numbers read from a file.

Thank you!  Let me know what I have to do!

The first thing I'll do is integrate in my patches, and then ask to have
them removed from the "patches" page.  :-)
