Why can't I stream videos from some websites? I have downloaded the latest version of Flash Player and I can't stream videos from some websites. Youtube works fine, but sites such as streetfire.net and moviephone.com first have to upload the whole video into my computer for it to THEN play. On Youtube I click on a video and it plays automatically.

Apparently there's a bug on flash player and they not going to update to.
Try this >>>>>>>>> Adobe Bug and Issue Management System (http://bugs.adobe.com/flashplayer/)

Flash player bugs

I would suggest you to update the version of flash player and it will work.
