Bluray are either VC-1 or H264 ...
You can of course always do the decoding in software only. A C2D at
2.66GHz is usually sufficient

It all depends ; you may have a 8400GS that isn't based on the G98 chipset.

If it's a 256MB card, you can be almost certain that it isn't.

If it's a 512MB card, a good indication to know if you have a VC-1
capable is if the card run at 657MHZ...

The definitive test is :

compile the utility and see the capabilities it reports: it has to show VC-1...

But then you loose half the resolution !
SD in Oz is interlaced: 576i ... you definitely don't want to do
one-field on this... And most nvidia card would do temporal or advance
on SD signal anyway
