Asslamo alykom wa rahmato Allah wa barkatoh.
Yes, there are many ways, but I prefer downloading from site!!! If you want to download any video from youtube, you should follow these instructions;
1- Copy the URL of the desired movie ( Address)
2- Paste the URL on in the first place (below the word download)
3- after that the picture of this scene/movie will appear on the bottom of the site (youtubex)
4- click on download beside the picture
5- After downloading this scene/movie (rename this file to (something.flv) something means the name of the file that you have downloaded.
6- Now, you will have to watch it by VLC. If that didn't work, you will have to rename it to .wmv(if you change it to .wmv it will work with the other players, such as media player, realplayer,...etc.
I hope my information is going to help you.
