Problems with Quicktime on iphone?

[jmdj1994]

I have a non-jailbroken iphone 3g and I just upgraded the OS to 3.0 last week. Since then I have noticed sporadic (but becoming more common) problems with quicktime. Whe I watch videos on daillymotion, I get a lot of error messages saying "this movie cannot be played" or a new one is "you don't have authority to access this movie" Most of the time this can be resolved by reloading the page and trying again. The last couple of days though I have noticed that when I tap a play arrow on a video that I want to watch it will only play the audio and instead of the video it's just a white screen with a quicktime logo. However, I can go to my imac and watch it fine or I can watch the same video on quickime on windows xp and I don't have any problems. Any tips or suggesstions? I last synced with my imac about 3 days ago. Thanks a bunch in advance!
