What can I say, Berni, you da man! :-)  After messing around with
lots of combinations today, I finally found that my so-called high
quality LaserDisc looked a lot better if denoised (but not sharpened)
and with a q value of 8.  I left the bit rate alone, though.

Sheesh, it's gonna take me a long time to get good at this.  I hope I
don't annoy the crap out of everyone meanwhile. :-)

Oh, and I finally posted a patch to the mjpegtools web site.  Now
yuv2lav can do the audio at the same time it does the video.  I also
posted the script I use to record.

My next patch, also to yuv2lav, will allow for A/V synchronization, by
either adding or removing a frame every so often.  Since my sound chip
is separate from my video card, the sampling rates are slightly off, but
I found the error is constant and repeatable.  I discovered, by doing
long recordings and then hand-adjusting the A/V sync near the end, that
I need to delete every 30,500th video frame in order to fix the problem.
Actually, I don't delete a frame, I just blend 2 frames together and
output 1.  Also, I don't do frame 30500, 61000, 91500, etc., but instead
15250, 45750, 76250, etc.  That way, the average A/V sync error stays
less than 1/2 a frame.  This allows me to produce some pretty
high-quality recordings with my cheap hardware, which is something I
think Linux should support as well as possible.

I'd post the patch, but it doesn't yet allow one to _add_ a frame if
that's what you need to fix the A/V sync, and it's kinda hacked up.  I
want to rewrite yuv2lav to be multi-threaded, so there's a reader
thread, a writer thread, and one or more encoding threads; that'll allow
arbitrary frame insertion/deletion without mucking up the architecture,
and allow for better performance.

Is anyone but me interested in this feature?  If so, I'll get off my
dead butt & write it. :-)
