I've purchased macbook recently and it's got leopard 10.5.2 with latest updates.

Everytime I visit youtube or video.yahoo.com and play flash videos there, every single clip stops after 10-20 seconds.

I have another mac laptop, which is macbook pro with tiger on it. However, it has never had the same issue as macbook does now.

Anyone had the same issue and resolved it?

MacBook, Mac OS X (10.5.2)

    Try running 'iDelete QT and Flash Caches 1.0'

    Good luck,

    It did not solve the issue. But thanks for the app link.
    Has anyone had the same or similar issue before with Safari on Leopard?

    Many of the YouTube 'Flash videos', despite their .flv suffix, are mpeg4 files in a Flash container.

    If you are having problems playing MPEG4 video in Quicktime 7.4 (and Apple are aware that some users have had such problems) you should carefully check in

    /Library/Quicktime and
    /Library/Internet Plug-ins and

    to check whether you have any third party plug-ins that are not completely up to date.

    Current versions of Flip4Mac and DiVX and Perian do NOT cause failure alone or in combination. However the one SPECIFIC extension that ALWAYS causes the failure alone or in groups is 3ivxMediaImp. All other 3ivx extensions DO work. Remove only that ONE SPECIFIC extension.

    Please try this and see if it fixes your problem with QT Player, the QT Firefox Plugin, and iTunes not playing MPEG4 files (including mp4 files).

    Older 3ivx and DivX components are often incompatible with new QuickTime versions and are, in many cases, obviated by component packs like Perian.

    This is not the only explanation for issues with MPEG4 file playback in QuickTime 7.4 and later, however. The issue with videos from democracynow.org and others, for instance, is the result of that content not complying with MPEG4 standards (namely that they use bogus track dimensions). QuickTime had previously ignored invalid track dimensions but this was changed in order to support properly authored anamorphic content.

    The recent update to QT 7.4.1 has fixed a number of issues but some problems are unavoidable when working with non-standards compliant content. The standards are important for many reasons including keeping hackers from manipulating improperly coded web pages.

    However, there is a workaround (also the basis for why those files will still play in iTunes): there are a few ways to trick QuickTime into ignoring the invalid track data. For instance, rename the files .3GP and they'll show up just fine.

    You should also try this:

    Remove HD/Library/Internet Plugins/Quicktime.plugin.webplugin

    Then Repair Permissions and restart.

    Post back if you want a list of the plug-ins you should have in order to play pretty much anything in Quicktime.

    After I looked at logs, I started to believe that it's related to internet connection on leopard. I started a new thread on another forum : http://discussions.apple.com/thread.jspa?threadID=1431583&tstart=0
