So you're opting for a minimalist package that has a small number
of dependecies? That's fine by me. I'll make all optional features
disabled by default then (one will still be able to use them after
rebuilding the source package with certain commandline options).
Is that ok?

Also, I think the "runtime CPU detection" doesn't work properly, I've
compiled mplayer with every cpu-specific feature (i.e. mmx, mmx2, sse,
sse2, 3dnow, 3dnowex) enabled (--with-xxx) and I got signal 4 (invalid
instruction) upon playing any movie on my AMD Duron. Bug report coming
in soon.
