I know that on at least a couple occasions I have mentioned that you
do not need an analog capture device. Simply rip a section from
one of your DVDs and re-encode it. Motion scenes and lower values
of -q seem to tickle the bug (but the problem can appear almost any
time).
You might check with Bernhard Praschinger - I send him a DVD of test
data to give to you (if he happened to drive and visit you).

It's not as ugly as some. But there's still time to redeem yourself
and rewrite it into C so that the next fellow can understand it :) :)

It _can_ do a sericeable job BUT (and this is the huge caveat) you
can't _trust_ mpeg2enc - you never know when the artifacting/bugs
will show up!

Actually I'd hope you would resurrect and do battle with, and hopefully
drive a stake thru the hear of, the "-q" option. Make that thing
go away! Please! Specify a rate, a minimum and a maximum. THe
encoder should automatically, I think, adapt the quantization (-q)
with NO help from the user except for the desired average bitrate and
perhaps an absolute "do not exceed" value.

I might have the snippet of DV data I sent to Bernhard - I'll check
to see if I have it, otherwise you might talk to him
THe problem, as I recall, was quite ugly when it happened - usually
when playing with "-q" - lower values seemed to make things worse.
