Would this apply to 64-bit CPUs running 32-bit code? Or just to
machines running 64-bit code?
I have yet to become aware of any advantage to running Myth in 64-bit
mode, but the mpeg libs and possible commflag are where I would expect
to see a difference if it exists.
The theoretical benefits of 64-bits might well be negated by the
optimization over the years of the code for 32-bit environments.
