5 Video playback and CPU optimisations go hand in hand.

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