WebKit doesn't show the animation when loading the video. (bouncing box) and others issues like flatten video, not playing, etc.
What build are you running?

Can you reproduce in a recent nightly build? If you continue to see problems, please attach a screenshot of the window showing those issues.

I upgraeded to tha last WebKit version and the problem is solved :-). The 'Daily Motion Icon' bounces correctly when loading the video. Thanks! Oh, another thing: openvideo.dailymotion.com makes Safari crash when try to play a video.
Please file a new bug on the crash, with a stack trace.
