This guy does a great job at showing the hardware and software side of getting video in front of the church and onto the internet. This might be a good introductory overview to the equipment and software to kick start some ideas in your own church.

I just ran across this set of purchase guides for doing church videos. They are suggested equipment purchase lists for 4 different categories
$135
$1500
$5000
$20000
I have not checked out all the equipment, but thought this might be useful to share with churches looking to get into broadcasting their services.
