    video skips frames when hard drive activity


    When playing H264 videos with windows media player classic (or any other player), video skips frames when hard drive activity becomes high like when virus database updates, files being copyed or any other windows process reads data from hard drive. Seems like reading video data from hard drive has lower priority than any other process ergo video does not play smoothly, skips frames. I have tried to set the windows media player process priority to high but that did not help. CPU is not the proble, CPU is about 40% when watching H264 video. Is there a way to prioritize application data reading from hard drive?

    My harddrive is SATA 7200 rpm, I have 3Ghz dual core CPU and ATI radeon HD4800 1GB (with latest drivers)

    I DID NOT have this problem with Windows XP Pro with the SAME hardware.

    could be a caching issue, I would suggest using VLC media player. If that doesn't automatically fix the 'skipping', you can adjust the cache limits in VLC. I don't remember how to adjust the caching in media player... if it's adjustable.

    No its not cacheing problem. I have tried VLC player and other players with large buffersize, did not help. Come on, I did not have this problem with win xp. I hope I do not have to go back to XP

    Try using 'Media Player Classic - Home Cinema' (MPC-HC) with Haali Media Splitter as its external filter (both are included in k-lite mega codec pack) and set input buffer in Haali Media Splitter to something big enough, like 192000 or something, and set its decoder priority boost to enabled if necessary. Also adjust the audio-video sync accordingly in ffdshow audio or use AC3Filter as an additional external filter because it has an easier to use slider for that.

    Enable process priority above normal in MPC-HC and enable triple buffering in the control panel of your vidcard.
