It's good information in the right place, thanks.
For my forum I let the old code in too but uncheck the visibility so users only have the new code in the editor drop down. I change the ubb tag a litte bit so both codes work. Solved.
Do you ever try to bring videmo videos to work? It seems that the code is accepted (I dont see a printed code tag) but nothing happen. The viedeo dont come up.
