Is it illegal to download youtube video for personal use only?

Okay, i want to make a Youtube video, and i would like to use a free screen recorder for my computer to film myself playing minecraft, a game in which millions of people play, and i see millions of videos on youtube about it... I tried a few things,...

i have used converter to download some youtube music and i used it in my own youtube video, will my account get banned? ps. i saw lots of youtube videos are exactly the same, and i ...show more

I need to download a youtube video for a project and I need a programme that has no viruses and is free, I've heard of safevid.com, is that safe? I would like one that is fairly fast too.

i tried Vixy.com and it only downloads the first 20 sec of the video. i tried a few other things. i have been at this for days. i have a vid on youtube and i just want to edit it and add some other stuff and i'm pulling my hair out. going to go run on...

I downloaded a video editing program Corel, and I was wondering if there was any way I could convert the video so I could have it saved on my computer and used in the presentation.. Thank you so much!

A question of interest. Would I use up more of my monthly internet data allowance if I watched a video on the internet via streaming or downloaded it to watch later?

I've been told to use MOZILLA, keepvid, vixy.net and a few others but none seem to work. Don't tell me what to use... Tell me HOW!!!

any other site but youtube
