Now that you are experiencing the fantastic CPU savings of vdpau, you
may find that the cpu power saving configuration kicks in.
(cpufreq/powernowd/etc)

With the CPU underutilised, the cpu speed drops to the lowest clock
rate, and (depending on your mobo/chipset/cpu) this can also slow the
bus (pci/pci-e/disk/memory etc).

If you do experience stuttering, make sure you turn all power-saving
modes off and retest. I personally
have the cpu's drop to their lowest setting, while a friend finds
stuttering when the cpu speed drops
because their chipset also reduces (throttles?) PCI-E bandwidth.
