I bet that purevideo and NV cards do well. I just kind of object to NV for various reasons.
I don't have the latest hardware leveraged decoder, though. that's prolly my biggest issue.
card is passive cooled (which limits me) ati 1650pro. it SHOULD have enough accel but I'm not 100% sure my player uses all the latest api's. hard to understand all of what goes on under an opaque cover...
I do have the latest direct-x and ati drivers. I also use a recent media player classic and it -seems- to have selectors for overlay vs 'that dx9 thing' (I'm not a windows guy!)
so I'm thinking I have some hardware accel support but maybe not the best I can get from this card.
in terms of gig-e chips, I'm not sure if they have earned their way yet. most desktop gig-e chips are still inferior to quality (intel) 10/100 chips. the intel 10/100/1000 chip is still (perhaps) the best but almost no desktop comes with the eepro1000. I'd still personally trust a dual quaity 100 vs a junky desktop 'realtek' gig-e. (it was very true for pci based ether chips. maybe less true with pci-e based ones, though).
but clearly the ether requirements are not as straining as you or I would have thought. disk i/o is mellow and net i/o is mellow. what is NOT mellow is video card heat and host cpu heat on playback!
