    Hi there, as an introduction, my MBP is 2.66GHz i7 with the NVidia GeForce GT 330M. I realized that after say a few minutes of watching a 1080p movie, or any video for that matter, suddenly the video gets choppy and after closing VLC, noticed that the whole system gets a bit laggy. Is this common? It's been doing this for quite some time now but it's just getting to me now. Can anyone please offer me some suggestions and possibly a cure for this? Thank you for your time.

    How much RAM does it have? Check the memory usage of VLC after a movie sometime to see if it's having problems re-allocating memory.

    Check the temperature of CPU.
    Maybe it is running hot, and throttling down.

    I've got 4GB of RAM. And I've checked the CPU temperature, and it's at 72 degrees with the fans running at 5000RPMs. After 23 minutes of VLC playing 1080p it uses about 173mb of real memory.

    I'm guessing this fixes whenever you close the lid/restart?

    Since I'm using an Apple Cinema Display, it fixes when I restart it, yes. I'm just not happy that that is the only solution to it. Is it?

    If that is 72 degrees C then that is WAY hot.

    163 degrees Fahrenheit on a Macbook Pro is far from too hot.....

    So does that mean that the temperature is too hot then?

    My Lenovo used to get to 96C when watching HD movies before I got the hardware accelerated codecs. Make sure you have the latest VLC. If VLC doesn't support hardware acceleration on OSX then get XBMC. XBMC supports HW acceleration. It is the best player I have seen. The error handling is the best also, the audio never goes out of sync. I have had several MKVs which had corrupted video and it played them very nicely.

    Never tried XBMC before, dloading it now. Is it normal for the system memory to have only 115mb free. Right now it's showing that 3.76 GB is being used.

    No, your temperatures are very normal. 163 F is nothing to fear.

    Says you? Max Temp on the i7 is 100C. 72C is nothing.

    I installed XBMC and it seems alot better now. What's wrong with VLC? The only gripe I have is that you can't boost the sound like how VLC does. Are there any other alternative for VLC than XBMC? Or can I do something so that VLC doesn't act in that way again?

    I would really appreciate any further suggestions on the issue as I've been experiencing the same thing as the OP.

    It's frustrated me to no end finding that my brand new 13" MBP is lagging harder after a movie than my 2009 model Unibody MacBook.

    Just downloaded MPlayerX from the Mac App store. Having a go at it now.

    I had the same problem. It was due to not enough disk space. Now I can watch a 1080p without a problem.

    The problem is RAM related, it will write alot of data to the hard disk :eek:

    What is XBMC, is it a player like VLC?

    Try it, it's free from the Mac App Store. Is it really RAM? Then if it is, I really want to upgrade to 8GB of RAM. Is it necessary though?

    This worked for me

    I had the same issue.
    I found that changing a preference in VLC provided smooth playback.

    Go to Preferences (⌘,) click All preferences in the bottom left corner.
    - select Input/Codecs, then within that, Access modules, and finally within that, File.
    - change the Caching value (ms) to 800.

    Lastly, do not be concerned about the temperature of the computer. In the unlikely event that you manage to get it anywhere near hot enough to do damage, the machine will automatically shut down to preserve itself.
