That's not at all true.  The only time I have ever heard of clock 
stepping causing problems with VDPAU playback were on older AMD systems 
using integrated nVidia video.  The memory controller would downclock 
with the processor, and since the graphics chip had no memory of its 
own, it would be starved for bandwidth and stutter.  This is not the 
case when using modern processors, and was never the case when using 
discrete graphics.
