    Vista itself requires minimum 1GB RAM to run smoothly.

    If play x264 encoded movie/video, it requires 1.5GB to 2GB RAM and CPU should be 3.0GHz (single core) or 2.0GHz (dual core) with 1MB L2 cache or more.

    Most important is you should have a pretty good display card (eg. Geforce 7600GS/GT with 256MB) fast enough to render the X264 or H264 source.

    Here is the spec from Microsoft Windows Media HD page(http://www.microsoft.com/windows/windowsmedia/cont...

    Minimum Configuration

    (to play 720p video)

    Windows XP

    Windows Media Player 9 Series

    2.4 GHz processor or equivalent

    384 MB of RAM

    64 MB video card

    DVD drive

    1024 x 768 screen resolution

    16-bit sound card

    Speakers

    Optimum Configuration

    (to play 1080p video with 5.1 surround sound)

    Windows XP

    Windows Media Player 9 Series

    DirectX 9.0

    3.0 GHz processor or equivalent

    512 MB of RAM

    128 MB video card

    DVD drive

    1920 x 1440 screen resolution

    24-bit 96 kHz multichannel sound card

    5.1 surround sound speaker system

    Below are the HDTV Playback CPU Chart from TomsHardware

    This is a simple but effective benchmark to determine if a processor is capable of taking on high definition content. We played the Blu-ray HD version of James Bond Casino Royale and tracked the processor load over a period of 60 seconds. Most single core processors - and even some dual cores such as the first Pentium D - cannot play the 1080p movie smoothly, if at all.

    Below are the experiences and configurations from other people around the world.

    I recently built myself a media box, just a cheap one I frankensteined from some old parts and new gear. Here are the specs:

    ASRock P4VM890 Socket 478 Max Bus 800Mz SATA150

    2Gb DDR SDRAM PC3200

    Sapphire Radeon X1650Pro - Radeon X1650Pro VPU w/512Mb DDR2 & PCI Express

    Dual 750GB Western Digital Caviar SE16 SATAII-300 7200RPM 16Mb OEM

    PENTIUM 4 (NORTHWOOD) 2.4Ghz

    >>> upgrade to >>> Prescott at 3-3.4Ghz (1M L2 cache)

    Now I have CoreAVC installed and most of my x264 files play fine.

    I can tell you that I am running Vista Media Center, on Pentium 4 2.4GHz, with 1GB RAM. All movies are working very good.

    So.. I believe it's the software. not the hardware.

    CoreAVC is working great on my slow system.

    Try installing the free VLC player, which often makes X264 watchable on slower systems. I have an AMD 3200+ CPU (32 bit, single core CPU 2+ years old) and VLC is the ONLY thing I have that enables me to watch X264/H264 at all. Your video card should be fast enough to render X264/H264, so try turning on hardware acceleration, if you can, in whatever program you are using to watch these videos. The much hyped CoreAVC codec is essentially useless on my system. I'm sure it works great - if you have a powerful enough CPU.
