Video playback and CPU optimisations go hand in hand. One video I have had for a long time, I could never play it at all on any of my computers and I could not beleive what I saw next... I got a new PC and thought to give it a try. It worked painfully, skipping and using 100% of one of my CPU cores. I was sad and thought this video might have been corrupt. After a wave of cleanup, I had removed all CPU optimisation flags from my make.conf (I was originally negating many, like -sse, etc, so I left it "to my profile" to choose what was needed) and recompiled everything. After that, the same movie played in the best quality I had ever seen and CPU usage was below 5% !!!! I was even able to open 12 movies (4x3) all playing at the same time (this was unthinkable before I optimized my system). Anyway, keep in mind that my particular starting scenario was that I had "un-optimized" it long ago! Good luck!
