Why does my Macbook 2009 May 13 inch lag in HD Flash videos on my Mac?

I know you would assume it was my 2.1ghz dual core processor and Nvidia 9400 256mb card, but when I play 720p and 1080p hd mkv videos on my computer they run fine. So, why would Flash HD struggle but MKV files play fine? Is it the MAC OS that is causing the lag, or something related to Flash? 720p flash files on youtube lag a little bit, but 1080p flash videos are extremely laggy. A lot of the hd videos on youtube don't even look like true 720p or 1080p because the bitrate on them looks low, yet my Macbook still struggles to run Flash HD.

Hello,

It could be that Flash video is much heaver on the CPU then normall video files,

only thing i can think of, Hover you mouse over a Flash Video, Right click with your mouse and open the settings panel.
There you have a check box for Hardware Acceleration, If its on, try off. Is it off then try on thumb.gif
