Herman Robak found out that the problem is not the JPEG encoding. It's the DV decoding by dvgrab.
In dvframe.cc (dvgrab code) the "quality" is not set to "best".

decoder->quality = DV_QUALITY_COLOR | DV_QUALITY_AC_1;

Should be:

decoder->quality = DV_QUALITY_COLOR | DV_QUALITY_AC_2;

If dvgrab is modified and recompiled, then the grabbing maintains the DV quality.
