you can left out xvid
libavcodec is enough

opengl has no any sense on linux, linux ogl drivers are shit
it's usefull on SGI and some other playforms without Xv but good fast opengl...

arts? mplayer has no esp or arts support
nas? dunno what's taht, you can left out
alsa? yes, include it. many card has no/broken oss drivers
also include sdl, it has good interface to esd/arts/nas/etc

dunno

yes

yes, it is required for many new formats, like .wmv files or divx audio

no. you should NOT touch --enable-sse etc. --enable-runtime-detection si
enough, it will compile all extensions
