Really glad for sharing good things with good people. God bless the
Hungarian and all their associates who keep this great MPlayer/mencoder
program so useful and do free... I would donate if I weren't  nearly
bancrupt with my poor man meagre investment, no room here to discuss
that though...

So, mencoder is the way to go...

I wish I could address these queries, but neither do I have sufficient
expertise, nor time.
Besides, Reimar has answered some of them.
But take a look at the longer discussion, previous to the link I gave in
my last post:
http://lists.mplayerhq.hu/pipermail/mencoder-users/2009-November/thread.html
You can just search by subject:
composite input a/v sync issue
In fact, to try to answer your questions, I would need to hark back to
what Reimar and other said to me in those posts (I don't bear notions
and others better than computer data in the mailing lists)...
What I can do is, I'll take a look at the last encoding commands and
options, as I have them somewhere, and they give somewhat better results
than what I have already written on the list and post them back.
They result from my further VHS-to-files work that I did after I found
the "-forceidx hack" on VHS being captured encoding...

Wish there were!

You're appreciated.
I'll be back to post what I promised above, God willing.
