No, the numbers are not swapped. In mode 1 mplayer ended up dropping
about 30% of the frames, which is why it uses less user and real time.
Cpu runs at 100% with no idle in mode 1.
In mode 4, cpu is at about 88% with 12% idle, and no frame drop. The
significant thing is that the system cpu time on Xorg is cut in half,
even though its processing more frames.
