    Hello

    Recently purchased DV4-1000ea as follows;

    2.26Ghz P8400 Core2Duo
    2GB RAM
    250GB HDD
    256MB Dedicated (1024MB Shared) NVidia 9200m GS.

    I liked the idea of the laptop having a HDMI output to connect to my TV to watch movies etc downloaded on iTunes. I thought the graphics card was going to be ample given that my housemates Macbook with 32mb shared graphics works just fine.

    However, I am really disappointed with the graphics performance playing High quality video, in particular, H264 Quicktime files.

    For example, I have downloaded a few 720p trailers from the apple website and torrent sites and when playing, the videos are choppy in most scenes and speech is not in sync with video a lot of the time. This is true for display on the laptop screen, as well as display on TV via HDMI.

    I have checked CPU usage whilst such clips are playing and it's running quite comfortably at 40-50%.

    I have downloaded the latest NVidea drivers from the NVidia website (version 7928).

    Also, even music video previews in itunes (and subsequent previews) are choppy and out of sync whilst playing. I have tried apples suggestions of turning off 3d accleleration for DirectX but it makes things worst.

    Any ideas? I have tried a couple of 1080p clips from the microsoft website (WMV) and these work much better!

    surely my graphics should be able to handle itunes video/tv shows without problem??

    thanks

    Darren

    I would have thought so. The GeForce 9200 dedicated GPU is supposed to be roughly equivalent to ATI's integrated Radeon 3200 GPU in the dv4z, and my dv4z plays 720p x264 and Blu-ray vids just fine.

    Check your memory usage in Task Manager (ctrl-shift-esc). And look for background tasks chewing up CPU time.

    i would install vlc player and try using that to play videos. it has built in a bunch of decoders you may be missing. if it plays smooth in vlc you know its a decoder issue. also if you havent yet make sure you install the divx decoders. just search for divx.
