Perian is a great tool for playing various media types within Quicktime natively, including FLV. For some reason I'd never bothered to try it with ProPresenter. Turns out that you can natively play an FLV file quite well in ProPresenter. It obviously has the same quality as the FLV, but if you need to use videos published for the web in worship this is a perfect solution. This morning just as a test, I pulled an FLV straight from our web site, imported into ProPresenter and it worked flawlessly. Outstanding.
