Thanks Diego... I wasn't exactly expecting that from you, but that's
very nice of you. :-)

I agree with you... Though I do think there is somewhat room for
improvement... I think I heard people here hate to hear about
"profiles", but I can't help thinking that many (at least _new_) users
would like to have presets like lame has (medium, standard, extreme).
For what I have seen (I had a look at ve_* parsers), presets don't mean
users can't modify/add options that were activated by the coded as long
as the presets can be parsed first, then the additional options, that
might reverts some settings.

lavc being currently a tool for experts doesn't mean (I my humble
opinion) it can evolve in a nice, easy and tunable codec.

I didn't promise I would do it, you know! ;-) At least you can count on
me to add it on my todo-list! ;-)

I subscribed to this list. I'm gonna wait a little bit before posting
there to figure out what the policy of that list is... just like I did
for mplayer!
