how do I download U-Tube videos to computer

I use Firefox and Video Downloader Professional (a free program) to copy u-tube videos to my HDD. In fact I am in the process of saving over a hundred u-tube videos on wood working that I plan to save to a DVD and plan to also put on my tablet to view later at my convenience. It works great. :)

Although it has some innocuous spyware in it, you can use MP3Rocket:

MP3Rocket

It has a powerful search engine to search for music/video and download and save as a ringtone/video/audio etc.

You can also do what you want to do and copy and paste the URL of a YouTube into the program and save it to you PC.

The only videos that are locked are any that have an Adult Age restriction on it.

If you are using Firefox browser
Options
Add-ons
Get new
Search YouTube
Or just install "Flash down loader"

As noted some videos are locked and cannot be downloaded

I use firefox and an add on called You Tube video and audio downloader

Link to its home page

NOTE: Some files can NOT be downloaded.

I also have You Tube Video Downloader on my Android phone.

Open You Tube and find the video you want. Select the URL link for the video. Open www.SaveVid.com in a new tab and paste the link in the appropriate box. The website should provide you with several options to download the format you prefer. SaveVid is a great free website to transfer videos to your own computer.

do a google search for "Free You Tube Downloader" then just pick one and follow download instructions. After download, follow instructions for use.

Added note: You tube changes their code very often, so you may have to download several before you find one that works, and then that one may not work for very long.
