I am creating a DVD from a bunch of AVI's. When I go to create it, I get a message saying that the TV Standard of the assets is UNKNOWN, and I should change it. But when i click the assset, and the information is populated on the right side of the screen, I can't over-write the UNKNOWN with NTSC. I also can't find any other place to do it. I'm trying to create the DVD anyway to see if it works, but the error message made me nervous. Any advice?

I am running the latest version of SVCD2DVD
