Objective-C iPhone - YouTubePlugIn.webplugin/YouTubePlugIn warning

I'm trying to play a YouTube video within an iPhone app using the technique in this URL http://iphoneincubator.com/blog/audio-video/how-to-play-youtube-videos-within-an-application

The technique works fine and the video plays fine, except that I'm getting this warning. warning: Unable to read symbols for "/Developer/Platforms/iPhoneOS.platform/DeviceSupport/3.1.2 (7D11)/Symbols/System/Library/Internet Plug-Ins/YouTubePlugIn.webplugin/YouTubePlugIn" (file not found).

That does slow down the app for the first time I got the warning. Seems like a lot of people is getting the same warning, but none of the forums I read seems to have the solution to get rid of the warning.

Do I need to download something or do specific things? I also tried adding the YouTube framework from "/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.1.2.sdk/System/Library/Private开发者_运维百科Frameworks/YouTube.framework" Doesn't seem to solve the issue.

Please enlight.

Some clips might not play in mobile devices. Check if you clips does.

The "/Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.2.1 (8C148)/Symbols/usr/lib/dyld' has changed; re-reading symbols" warnings can be ignored (the clips should play anyway if it is available on mobile devices).

Note. I don't know the correct reason why some clips don't play on mobile, it might be a transcoding issue (not being transcoded for mobile) or some publisher settings. Would be interesting to know.

You need to run your app on the device. The Simulator doesn't have the YouTube app.
