Instructions
Install the latest version of Java and Flash directly to your PSP. While your PSP is still connected to a Wi-Fi signal, go to your Settings Menu. Look for the Flash Player selection and click on it once to enable your system to use Flash.
Visit YouTube on your Sony PSP and select a video to watch. If you have the latest version of Flash, the video should play automatically. However some people may still experience problems, which requires using a proxy server to watch YouTube videos.
Search for YouTube videos while on the website. When you find one you like, click on it and when the page loads, look for the information box on the right hand side of the screen. You̵7;ll find two links: a URL and an embedded link. Copy the URL from the top of the box.
Find a proxy server such as Vixy. Visit the site using your PSP by entering the URL of the website in your browser. These sites work by automatically converting websites that you might otherwise not have access to, but you̵7;ll still need to convert the video from YouTube.
Paste the URL into the search box on Vixy and press Enter. Give the site a few seconds to automatically convert the file into a different type that you can use and watch on your Sony PSP. Once the process is complete, you can instantly start watching the video. If you want to watch multiple videos, copy the URL from each one and paste it in the box on Vixy.
