For about a few months now, flash videos (specifically Youtube and Liveleak) have been stalling before they play. The video will be black for around 30 seconds before the video actually begins loading or it will just give me an error. Here's how it looks like:
Notice how all videos on the sidebars appear white as well. I have tried reinstalling flash (stops at 50% "Failed to Initialize," have to use offline installer), using different browsers, using other computers on the same connection (loads fast), and switching Youtube to HTML5 (fixes it, but other flash websites still have the problem.)
