With 128M, it's not surprising that you can't decode HD video; the RAM requirements are just too close to (or exceed) what's on the card.
Thanks for the quick response.
nvidia-settings is showing that the Quadro FX 570M has 512MB memory, of which I assume 384MB is borrowed from the system RAM. I am just wondering if Nvidia has any plan to make use of the TurboCache for VDPAU? I heard that it works in Windows.
