OK, I'm finally upgraded to v2.6

I encountered a problem.

New videos upload fine. Links work ok and all is fine.

Links to existing videos doesn't work.

For example:
http://www.mydomain.com/view/76/dutch-f16/

only shows up as:
http://www.mydomain.com/view/76//

The videos work fine in admin, but the links don't work for visitors.
I thought it was an .htaccess problem, but uploading the new one didn't resolve the issue.

Any thought on what I can do to get my existing video to work again ?
