[mythtv-users] Lots of confusion as to which card(s) to buy for vdpau

So what is the point here?

The idea is to shift processing power from the CPU to the Graphics
chip.  What is gained?

I did a small comparison based on Tom's Hardware power consumption and
Newegg product cost.

8400GS  system power 136 watts video card $30,  AMD 5400+ CPU 65 watts  $68
8600GS system power 172 watts video card $64, cheapest CPU $38 45 watts

I assume that the vdpau system saves 20 watts by using a slower cup
than what Tom's Hardware used and add the

video card and cpu costs:
vdpau system 152 watts $102
standard system 136 watts and $98.

The non vdpau system wins.

I must be missing something.

What I am saying here is that computing power is computing power. Put
it on the graphics card or in the CPU it is still
computing power. I guess if adding a new graphics card to an old
system that is sitting around makes it usable, that
could be a big savings but I don't see any other advantage. If vdpau
worked with an 8400 like I was assuming, that
would be another story but if you all are saying it doesn't, then I
just don't see the point, at least for a new system.
