My computer won't play videos, especially youtube videos?

1. Most YouTube videos need JavaScript enabled. If or when JavaScript is enabled try it again, and if that does not work make sure you have a plug-in.
   

Hi, the videos may not play if the Adobe Flash Player in the computer may corrupt or not updated to latest version. Please download and install the latest version of the Mozilla Firefox and then download and install the Adobe Flash Player. Please restart the Mozilla Firefox and visit the Youtube. Now the Videos should be playing.

Please search in google as Mozilla Firefox and Adobe Flash Player to get the download link for the Mozilla Firefox and Adobe Flash Player.

I've had this issue too on my HP G72.
Install any updates to Adobe's Flash player. If this doesn't work try reinstalling Adobe Flash.
Also make sure to install any available updates to your computer. Hopefully these tasks will work. My Youtube video's randomly started just showing black a few months ago, especially whenever a HD/even 420p video was played.
Best of luck!

Start from repairing your Windows registry and fixing your Windows errors that become the cause of many browser and applications errors causing a conflict situation.

* Test your computer for viruses and spyware.

* Run SpeedTest to test whether you have sufficient bandwidth available to smoothly play YouTube videos without causing the site to run slower.

* Disconnect your internet and then reconnect it to know why is YouTube slow and whether it is because of the poor internet at your side.

* Disable ads through some of the browser plug in that will allow you to run fewer background services while you are playing videos online.

* Try to change your flash player version. Although the YouTube has started to stream videos through a new technology there is still a large number of web sites using the flash platform. So it is a nice idea to try to change the flash player version to play videos without crashes and error messages.

* Try to change your browser. One good browser to play YouTube videos is Chrome. If you have not tried that go for it. Also contact your ISP provider if they are limiting your bandwidth at specific durations of the day.

The above solutions will most likely fix and answer your question why is YouTube slow on your computer. However, it is highly recommended you follow all the guidelines especially optimizing your PC Windows for internal registry errors through RegInOut

turns out you have an iBook G3. Your computer is really too outdated to be expected to play video properly. You can add more RAM but it really will only partially help you out. the G3 computers just aren't made for decoding streaming video, especially now that YT has HD video.
