Default Re: VDPAU testing tool

I have installed a Sparkle 8400GS PCI in this machine. (PCI, not PCI-e)

Before the 8400GS I had an FX 5200 which could play AVI's and ISO's through VLC satisfactory. MP4 and H264 was non-satisfactory. Many freezes on MP4, 1 FPS with H264.

I installed the 8400GS, and H264 still is displayed at 1 FPS. Worse is, that oridinary videos like AVI's and ISO's have become unwatchable as well due to many freezes. H264 is at a 1280x720 resolution.

VLC 1.1.12 is using hardware acceleration, and when started from the command line it confirms that HW acceleration is used. There is however NO difference at all between HW assisted and non HW assisted performance.

When I play movies thru MPlayer, (-vo vdpau) mplayer tells me the computer is too slow, and audio lags about 10 seconds.

I am running the same VLC on an Intel Atom 1,6 GHz with NVIDIA Ion. That decoding is fully satisfactory.

Below the test results for qvdpautest for the 8400GS.
