Projector connection

[Rosstaylor]

I have prewired into the fabric of the building a standard coax cable in my new house. The coax runs from where I want my DVD/Sat etc to a point on the ceiling for a projector. I now realise it should have been an S video cable. Is there any way I can make it work with the coax cable by adapting/converting conections? I notice some projectors have built in tuners with a coax input for that, would it be possible to send the DVD/sat signal thru that input? PLEASE HELP!!

Well, if you've got a composite video out on your other devices, and a matching input on the projector, you could connect it that way, but the picture quality won't be nearly so good.
