Troubleshooting videos, something to do is enable hardware acceleration, but IE9 doesn't let me uncheck the option. This under Internet Options - Advanced - Accelerated graphics.
So, what's happening? Already updated the driver for the Mobile Intel (R) 945 Express Chipset Family.
On systems using an Intel(R) Graphics Media Accelerator, the hardware acceleration is managed and controlled only by the video driver, with no option to manually set ir or control its level.
If your Internet browser does not let you disable certain options you might need to check with its developer to see the reason why.
Concerning troubleshooting the videos you are having issues with, we also suggest you to check using the latest media player and codecs available for your system and try using other web servers.
