I don't know that that is a definitive test, I've seen blue screens
without XvMC before.

I look in the frontend log.  Start Mythfrontend from a terminal
window, and watch it's output.  When you start watching a show, it
will report if it's using XvMC or if it can't and why.

Also, what hardware is your remote frontend on?  Is this an mpeg2 or
mpeg4 file, and is it HD or not?

I've also seen tweaking ALSA helps me to lower my CPU usage, once I
switched to using SPDIF pass through, things seem to lessen the load.
