I have this same problem. Started about a week ago. I couldn't play any videos from sites like blip. I figured it was slow connection, server problems... but I just tried an experiment. I let an episode of deep space nine load for over an hour with the little flash thingy circling endlessly and no video playing. Then suddenly the video started playing and the entire video had loaded.

So, obviously there's some setting that's gone wacky. Youtube videos play right away and buffers normally. I'd had this problem on virtually every flash video site except for youtube and Hulu, the videos start playing as soon as they've buffered a little. Same problem on every browser I tried.

And, no I haven't found any real solution.

Haven't tried it, but this wait for it to load thing is working for me. It's taking forever but the videos are playing eventually. Flash is downloading the entire video before the swirling thingy goes away and the video plays.

No settings have had any effect, and strangely downgrading to flash 10.3 had no effect so if it's not flash I can't begin to guess what it might be.

same thing is happening with me, flash is only working on certain flash video tube sites, worldstarhiphop.com is not working properly only the short videos are the ones that load properly, xhamster.com is not working properly neither....yet Youtube loads perfectly and normal...I've tried uninstalling the current flash version and downgrading and nothing...same results....i even tried uninstalling my antivirus thinking it's not letting flash run correctly....and still.....nothing..... can you guys get this to work?...its been about a week already....Thanks!

That's yahoo. They refuse to fix it. I've changed my passwords dozens of times.
