KEVREV I was drafted into the AV position at my local church 'cause I'm a geek. Originally I was stuck with SundayPlus on a PC. Finally switched to a Mac & ProPresenter. I am a VERY happy camper now! The program is simple to use but gives us the power to have the text display & background display controlled separately. It works great for our song service, announcements, & video clips.
Not to mention the fact that it keeps getting better - for free! They added the DVD clip feature so we don't have to switch over to our old DVD/VCR input anymore. And version 3.3 now adds Live Video which I will be excited to test out.
One of the primary reasons in switching to Mac & ProPresenter was to make it easier for 'non-geek' volunteers to run the AV system for services. Trying to teach someone on SundayPlus did not go well for us. (At one point we bought but didn't even attempt to teach MediaShout.) ProPresenter has the features we need on the best OS around. It is used in conjunction with Keynote (for sermon presentations) & WireTap Studio (to record sermons live as podcasts for our website). All apps play nicely together on a Core 2 Duo Intel iMac running OS 10.5.2. With ProPresenter I can stop worrying about the technical stuff and start getting creative. That's what Mac software is all about.
