    OK I have the most annoying problem with my macbook. Its a Core2Duo blackbook from late 2006. For the past few months videoplay back has been horrible. What it does it when I am watching some video the audio and video will skip than miss a few frames than jump a few than just freeze or crash itunes or vlc. I have no idea what us causing this if anyone could help it would be greatly appreciated.

    Playback of any audio/video content on a Mac is going to be related to QuickTime. Check if you're running QuickTime 7.6, if you aren't, update. If you already are, look in /Library/QuickTime. If anything is there like Perian, Flip4Mac, 3ivx, pull the component files out to the Desktop, restart the computer, and try playback again.

    Hmm, system doesn't have the integrated or discrete cards found in the unibody notebooks. I'm guessing you're trying to watch local files on the system, they're not streaming or anything? Open up a file and go to the Window menu, then "Show Movie Inspector." What are the audio/video codecs in use?

    if it makes any sense, stuff I download from other places works fine. Such as divx movies and stuff. It seems to be stuff downloaded from itunes is the worst, even in VLC. I added I bigger pic for the codecs it using.

    You kinda mixed up the order there :). You're supposed to run disk utility before reinstalling the OS. There really isn't a point to running DU after reinstalling. The A&I is about the third or second to last option before a non-preserving archive & install or an erase & install, which both seem a bit excessive.

    so I am sure its all heat now. I got the top keyboard area off my macbook and I am running HD video, ichat, mail, and firefox with 8 tabs open flawlessly. The macbook is running 20 C cooler than when its all closed up. So my question is, whats the best cooler for the macbook? I am not under warranty so I cant send it in.

    Plex is more efficient at decoding, thus your cpu will work less, thus your computer will not get as hot. Quicktime, VLC - they both suck.

    Also, what's the bit rate of your video and what's its container?

    Any Core 2 Duo Mac should be able to cut through 720p h.264/AAC like a hot knife through butter. Even a 2 gHz Mini can handle Blu-ray rips and they're at 1080p and 30 mbps bit rate (or more). How much RAM do you have and what other processes do you have running (from Activity Monitor)?

    2 gigs of RAM. I am tell you its heat. If I have the machine all sealed up the temp goes up to like 80C and skips and crashes with just VLC going. When I have the top off and the heat can escape it stays at 65C and runs smooth with VLC,firefox, mial, and ichat

    maybe the thermal paste wore out on the cpu? I don't know why this just recently became an issue. I am thinking if I get a good laptop cooler and put the macbook back together it will all be fine.
