    I've got one of the new Macbook Pros (late 2008). I have noticed some pretty bad video tearing while watching Netflix Watch Instantly, which uses Silverlight (Microsoft's answer to Flash). I have no tearing with Flash. (The effect is similar to the tearing seen when scrolling using the scroll bar--this happens when you click and hold the scroll bar, say, in Safari or Mail and drag it up and down. It does not happen when two-finger scrolling with the trackpad. Strange...)

    Now, my friend's iMac (with ATI) graphics has no tearing with Netflix/Silverlight. Therefore, I have concluded that this is an issue with NVIDIA and Silverlight.

    Has anyone else with a new Macbook/Pro (with the NVIDIA GPU) noticed this tearing issue with Silverlight media, especially Netflix Watch Instantly? If so, I'd like to get this some publicity in the hope of getting a fix.

    In the land of no hills and red dirt.
    Have you tried posting at apple's support forums and calling customer support?

    I sure have. Support was nice, and promised to send the issue up the ladder. It seems, though, that since these Macbooks are so new, and so is Silverlight implementation, that there isn't yet much being said. At the same time, I have noticed that others on the web seem to have noticed this problem, but I'm not sure anyone has yet narrowed it down to an NVIDIA issue.

    New MBP Unibody Video Problem

    I bought the 2.4 MBP in late October, 2008, so it's about 3 weeks old. I've used Macs all of my professional life, starting with the Apple II, so I know Macs, what to expect, etc. Unfortunately, I'm afraid I'm having a problem with the new machine.

    Start-up is painfully slow. It takes forever. My son tried to play World of Warcraft on it and said it was too slow for him to play (he uses a 1.8 GHz iMac that is rated slower than the 2.4 MBP.) I'm using an Apple Cinema Display with the MBP. If the machine goes into sleep mode, on waking, the ACD screen has all kind of video noise, stripes, flashes, etc. I have to restart the laptop in order to correct this.

    I also have problem when playing HD video. The response rate seems slow and sometimes jerky. I thought this is where the Nvidia 9600 GT chip was supposed to excel. Go figure. I am returning the laptop after Thanksgiving holiday. We'll see how much Apple backs their product.

    This is the first time I've ever been disappointed in a Mac. We'll see what Apple says.

    You most likely didn't switch the graphics card to the 9600 mode from the 9400 mode. The new MBPs have two graphics cards. Click the battery icon in the upper left, select Better Performance, and log off and on.
