Prior to the thread I read concerning download of YouTube videos, I decide to share what I know about downloading from YouTube. But since I am a bb10 user, I have only confirmed this method works for all users of bb10 (z10,z30,q5,q10 and q20) so android users and iphone users you could still make an attempt.

Step1: log on to youtube.com on your native browser and search for the video you want.
Step 2: once you search locate the url of the file you search for and edit it i.e you change http://m. to ss Eg. If the url is http://m.youtube.com/results?q=ima%20robot%20greenback%20boogie&sm=
Rename it as ssyoutube.com/results?q=ima%20robot%20greenback%20boogie&sm=
Step 3: hit the enter button and the browser loads and takes you to another link where you would see alternatives on what format you could get video
Step4 : choose any of the format and your good to go.
For better clarification I av attached some snap shots too. But if u still Don get, feel free to ask your questions. Thank you and that's all.

It looks workable. But I think video converter studio is much more convenient to use. It can detect and download the online streams automatically once recognize the video successfully.

Good thing you said so. Atleast your giving more alternatives to people.

Nice one op
