No.
You can download the Youtube application from the eShop if you want to watch Youtube videos, you can not watch video files such as mp4s, but if you upload them to Youtube you will be able to watch them :)
Yeah, you can download videos off youtube and watch or use sites to download song.
You could download Youtube videos with JAVA or any other Plugin by going on : http://downloader.me/. But you could only download it in a Mp4 format. Another option is to download a "Youtube Downloader" at http://download.cnet.com/YouTube-Downloader/3000-2071_4-10647340.html . Good luck.
I'm not sure if you can download kids videos but you might be able to YouTube them and watch them on your computer. If not, sorry!
Probably Google Videos, youtube or Disney.com XD
You can download YouTube videos using this videopower.me/tips/ct-download/download-youtube-videos-automatically/ It has a converter tool too so you can convert the downloaded youtube file to psp compatible format.
Sometimes you download a video when you click on the "watch" link- sometimes it is streamed to your computer (like YouTube)
Well if you just want to watch them...YouTube is key!
Flash Player you can download it at adobe.com for free.
While there are many websites if you search it, for me i recommand StreamFab Youtube Downloader. It can allow you to download not only videos of Youtube but also other plateforms like facebook, instagram, etc. dvdfab.fr/youtube-video-downloader.htm
When you play a video on YouTube, you send a request to the YouTube servers to begin uploading the video file onto your computer browser. This is what allows you to watch the videos on the website.
you can get on the Youtube channels videos will be present there and download or watch it online by streaming
