Most of you who edit/make vids might have already experienced this problem. Youtube has gotten rid of the 'share with all friends/contacts' feature in order to reduce spam/abuses. But consequently it has caused major inconveniences for vidders and regular users alike. I believe it's total BS and has only been done to further enforce the corporate monopoly and detract from the user's control over Youtube.
Anyway, I was looking for a solution to this glitch and came across a video on youtube itself. In order to share with all friends/contacts, go the URL box where the link of your youtube video is given, erase the word 'watch' from the link and type 'share_inline' instead. It should take you to the older sharing page.
If that doesn't work, instead of 'share_inline', just type 'share' and press enter. In this case, you will not be able to share with 'all friends' but with 'all contacts'.
Here is the video:

Hope this helped!
