Do SSE and MMX Use Flags Help?

I noticed that your supposed to include MMX and SSE Use flags when you want multimedia support, which I have not done. As it stands now, my video playback tends to studder at times. Might these flags help?

AFAIK. they do make a difference speedwise.
I have MMX, MMX2 SSE, SSE2 in my USE flags (which is supported by my processor ofcourse

)

Okay. xine-lib is recompiling now. Do I need to recompile anything else?

EDIT: I see a bunch of things listed next to "flags." Are there USE flags for all of those?

Unless it's listed here http://www.gentoo.org/dyn/use-index.xml, no.

To me, I'm curious about whether mmx is required when we have sse/sse2. I'm uncertain, myself.
