no, just would break build with older cygwins, hmm...

yes, surface locking seems needed on win also you should try to use an older 
vo_sdl.c. before Fredrik Kuivinen added the osd-outise-movie stuff, as 
directx doesn't like to create more than one hw surface it seems.
I think I can send you such version if you're too lazy to search cvslog, note 
that you would need to readd "directx" to the list of windowed capable 
drivers (as now "x11", "aa", ...).
