I was wondering if you could be more specific when you say "almost 
nothing"?  Could you give me some average values for 1080i playback?

I get smooth playback w/ slim and cpu++ but cpu % still seems quite high 
for me.  I certainly couldn't describe it as "almost nothing".

my specs:
x2 5000
1Gb DDR 800
Asus M2NPV-VM (Nvidia 6150/Nforce 430)
Mythdora 5: kernel 2.6.24.4-64.fc8
proprietary nvidia driver w/ UseEvents true

High Quality and Normal playback profiles are literally 1 fps slide 
shows which makes me wonder exactly what kind of hardware is supposed to 
be capable of using them.

I was  using a Sempron 3400 on this board and upgraded the cpu to the x2 
5000 when i upgraded to Mythdora 5 from MD4.  I expected to see 
substantially less cpu utilization on the new 5000 but the load seems 
only marginally less even though I no longer have any minor hiccups w/ 
1080i content.  All kinds of software changes so it is not exactly an 
A/B comparison but it kind of feels like no matter how much horsepower I 
throw at my frontend it always finds a way to use all of it while doing 
the same thing it did before.
