This doesn't use any GPU features. Good compatibility but otherwise not
recommended.

Same as gl just that it fails when you have driver issues that prevent
it from using the GPU. More like a debugging tool.

Practically outdated.

Recommended. Should work okay without further tuning but offers a lot of
them. Just play around.

Unmaintained. Use gl.

That should be USE="mmxext". No clue what's its name in cpuinfo but
since you are running something newer than a P3 it should be a safe bet.

PS: Have to tried mplayer2? It's mostly compatible but offers no
mencoder support but you can install mplayer to get that. It has better
threading support and some other minor improvements.
