yes, it seems that if you are using the same url in your videos and your videos are the same....youtube will bring down the hammer on you. They did that same thing to me last week. So i'm in the process of rebuilding my youtube empire.

If you use a tinyurl link, just make sure its unique to each video. Maybe make something like

<your domain>.com/index-a.html
<your domain>.com/index-b.html
<your domain>.com/index-c.html

and each html file will re-direct to your landing page you are promoting on youtube. That way each tinyurl link is unique.
