As a datapoint, Dell stopped putting hardware mpeg decoders in their 
DVD-equipped laptops at the time their CPUs hit 500Mhz.

Of course they were using highly-optimized code for the DVD player, so 
it might be better to say that 750 Mhz. is required to decode SD mpeg2 
in software. Myth does more than just play the file, so it would need a 
little more than just decoding would require.

So anything you can buy now, or even 5-7 years ago, should be able to 
cope with SD mpeg2 decoding by the CPU.

Of course h264 is an entirely different story.
