I can bet that nvidia video acceleration is required for fluid playback on that hardware. Check the cpu utilization and if it’s high then VA is not being used.

It would mean the CPU is the one being tasked with decoding instead of taking advantage of the 9400 decoding abilities.

I can also guess that the blueray demo uses a player that has the nvidia VA ability enabled (most do) and why it may play better.

As far as playing other media it will ultimately depend on the encoding, if the codec can handle VA, and the player.

So how do you explain the RAMDISK solution on Linux… The PC was just freshly installed too.

The HDD shouldn’t be the culprit unless it is badly fragmented, which if it is a new system shouldn’t be. Try running Crystal Disk Mark and it will tell you the average read rates of the HDD, but really a 1080p compressed video should be around 10 or 8 mbits/s which amounts to being around 1 megabyte a second. Think about it also as, how long did it take you to copy the movie to your HDD, if it takes you longer to copy the movie/clip over then the actual length of it, I can see that causing problems.

I’m not sure the videos you are playing, if their codecs are hardware accelerated on that system. I know I had trouble with my Asus N10j (which has an atom and the 9300m gs as well as a 5400rpm hdd), with that system a person has to do funky things to get it to hardware accelerate some codecs for HD video.
