    I've been having issues getting videos to play without lagging. By lagging I mean... it sounds as if like a half second is stuck on repeat. I have problems with online movies (YouTube, videos on news sites, Vimeo - any and all videos) at any size player and with QuickTime and VLC. I thought it might just be low processing so I just upgraded my RAM to 4GBs. I know it's not my internet speed because my roommates can stream full screen videos fine. I've cleared my cache and cookies, moved all unnecessary files to an external hd, and I try quitting all background programs running through the Activity Monitor. I've also tried repairing disk permissions.

    Computer Specs:
    Mid-2007 MacBook - White 13"
    Version 10.6.8
    Processor: 2.16 Ghz Intel Core 2 Duo
    Memory: 4 GB 667 MHz DDR2 SDRAM

    Hard Drive:
    Capacity - 319.73 GB
    Available - 160.51 GB
    Used - 159.21 GB

    Does anyone have any ideas on what I can do to maybe clean up my computer to make videos play smoothly? I'm out of ideas. Please let me know if you need any more information. Thank you!

    Unlike iPhones, iPods, iPads, and later MacBooks, Mid 2007 MacBooks have basically no h.264 video acceleration (see Tech Note TN2267: VDADecoder). But video up to 720p will probably run reasonably smooth on CPU grunt alone.

    Check if you have the latest Flash player, QuickTime, VLC with:

    Otherwise, while no video is playing the CPU use should be low. If anything else is using a lot of CPU, video playback will lag. Check the CPU use with Activity Monitor:

    You may use flash blockers like ClickToFlash to stop (other) websites from loading CPU heavy animations that disturb video playback.

    Turns out my Flash was out of date. I updated it so I'll see if that helps. Thanks for all the links.
