Recently, flash videos won't play smoothly

[Starbreeze]

I've never really had a problem with this before unless I was running too many things at once, but now it happens when nothing else but the video is running.  Videos on sites such as youtube, videobb, megavideo do not play smoothly even when fully loaded.  How can I fix this?

Do you have many processes running in the background? Have you tried clearing your Temporary Internet Files and Cache?

[Starbreeze]

Yes.  I have cleared Temporary Internet Files, and have nothing else running in the background.

Then it's your internet connection...

Can you please explain more on this part as to how videos run or displays?

[Starbreeze]

Hmm...
It's kind of hard to explain.  I guess you could say they're jumpy.  Starts and stops frequently, and when something in the video becomes really fast, such as someone running, the screen really starts stuttering.

Can you post the computer model and operating system? You may need to look for updating your video chip/card(if available) and flash player if they are not running the latest yet.

Right click the video in YouTube (or any other video site) and click settings. Go to the first tab, where you will see Use Hardware Acceleration and make sure you have checked it. Also be sure to update your GPU drivers.
