What's the format of the church video.
It may just be a matter of converting your video file; if I put a DVD in my dvd player which contains mpgs, it will not play them, but if they are converted to DVD format, there is no problem; I am assuming the same principle applies on hooking up to the TV, but others may correct me on that. (Not getting into mpeg compliance here).
If you have a program like Nero or Roxio, they should have components to deal with conversion;
otherwise, you can try the free divx to dvd converter; I have used it in the past successfully and when
I got the Roxio EMC suite, I found that the divx to dvd component appeared identical.
