You do loose some performance currently due to MMX not working under
64 bits.
      
Really? Are you refering to the sw part taking advantage of the HW? I 
haven't heard of any chip issues.
    

It doesn*t build w/o turning off MMX.
Well.. crummy! Why is that? (should I ask in the devel forum?)

Does anyone have benchmarks, or even off the top of your head knowledge, on the performance difference w/o MMX on 64-bit vs. w/MMX on 32-bit. For mythtv, is having MMX a decided "got-to-have"feature for performance?
