Hi, new to the forum. I purchased SVPro 8 a few months a go and really like it. My OS is Windows Vista 64, and I'm using SVPro 8.1. When I render a .mov file I get an error message about 8 seconds into it that states: An error occoured while creating media file .mov. An unsupported media type was requested. Sometimes it will give me the same error except adding another program is using this media type. I was able to render movie files before and don't recall changing anything or running any other programs. Thanks
