    so there is no need to scale down a 1080p matroska (mkv) movie, if the file has high@4.1 profile, you can simply use DxVA with just 2-4% cpu usage.
    my fw has 4500mhd GPU, and it's more than enough for video playback.
    You can not rely on CPU alone. Even the fastest C2D doesn't have enough juice to play BD without GPU assistance. So activating hardware acceleration is a must. The HD 3470 is more than adequate but only if it has 256 MB VRAM or higher. As for your 4500 GPU, wait until you stumble one that will get choppy on you. Not all BD are created equal. Some are more demanding, some are less demanding. Cast Away (Tom Hanks) for example, is more demanding. It is smooth with my Integrated Card but choppy when I tried it at store with Intel card.

    Where do you base this on Hendra?

    - "Even the fastest C2D doesn't have enough juice to play BD without GPU assistance.
    - The HD 3470 is more than adequate but only if it has 256 MB VRAM or higher."

    I find both statements questionable. The last one sounds like manufacturer's claims.

    I'd like to get to the bottom of this so I started a thread here:

    using HDMI to a full HDTV or to a 1920x1200 ext LCD only produces like 5 frames per second, video is very choppy, no way you can watch a HD movie on a HD ext screen.
    On the internal display/laptop works just fine.

    I am talking about a SR290 with HDMI/Ati video card.
