I'm running Windows XP. Using IE8, the youtube videos won't play. There is no warning or anything, just the video is black and there is no play button. On Google chrome, there is no problem with playing youtube videos. What can I do to play it on IE?

Well Sunkengarden, the videos you are watching on YouTube or any such websites are the Flash Player Applications. That means, the Browser on which you are trying watch the videos, needs Flash Player Application to be installed on your computer. Such traditionally most widely used flash players are Adobe Flash Player and Microsoft Silverlight.
While you are using Google Chrome, there is no problem just because of Google Chrome already have in-built flash player within it. But the problem remains for IE or other Browsers.
Different Web-Browsers use different types of Adobe Flash Players (IE type or Non-IE type). So, for best results, I recommend you to install both the IE and Non-IE Adobe Flash Players on your computer to have all the browsers play the videos without any problem.
Download the Flash Players by clicking on the following links:

• Adobe Flash Player for IE (IE, Avant,etc)
• Adobe Flash Player for Non-IE (Mozilla, Mozilla Firefox and other Geeko based browsers)

Try updating or install the latest flash player for your IE.

Download Flash Players
1. Flash Player 10.3.181.5 RC 1 (IE) - IE browser

2. Flash Player 10.3.181.5 RC 1 (Non-IE)


Hope it helps.
