I try to render to Main Concept mp4, and when I click on it in the drop down menu, it says that there is no template for that format. If I exit the drop down menu, then go back to it, that choice isn't even in the drop down menu anymore. It just dissapears. I have the current update 6.0D. I was instructed by someone to download the update to a cd, then install from that, instead of installing from the original 6.0 disk. I did this, it asked me if I wanted to overwrite the files that were already there, and I said yes. Still the same. Strange thing is that I also have Cinescore, and it is the same way.
