Hi Bernie, I had to recompile (re-emerge in Gentoo) mjpegtools with quicktime and dv included (with -f a the file size was over 2 Gig). Looks like I had the right idea but not the precise way to get there. Followed your instructions, but still not finshed. Note, I had to add -n n parameters to the yuvscaler because it did not recognize the format. Here is the problem:
