Actually the code of -fixed-vo was never beta (it's just a few if()'s),
but its usage was not recommended for users, until every (important) vo
driver are fixed to work correctly with it. It was added by me to help
vo driver developers test & fix their drivers for new vo specification...
It skips closing and clean-opening driver between files/titles, but it
requires special code in the vo driver to detect size changes and
handle re-opening (without closing first) differently than the clean open.
Afaik most vo still fails to handle this...

Maybe it's time to make a brave step - setup shields against users! -
and enable it by default, then run to fix all broken vo drivers quickly!

Also note that a problem exists with multiple files given on commandline,
when -fixed-vo is set for all (in config file or as first parameter)
and you set different vo driver for a file, example:

mplayer -fixed-vo 1.avi -vo x11 2.avi -vo xv

it will either crash, or break, or play 2.avi with vo_x11... i dont
remember which, but all bad... so who cares :)
