Anyone wanting to hook a Freeview decoder to a projector might be interested in a Samsung model available from Scan (http://www.scan.co.uk/todayonly/ ), which unusually appears to have an s-video output in adition to the usual SCARTs.
That's true, it's not clear whether the s-video is via a seperate connection or through the SCART. If it's the latter though, it's easy enough to buy an adapter plug for the SCART which allows you to connect a conventional 'mini DIN' style s-video lead.
As long as the device can put s-video out then you can use an adapter to pull that off the Scart socket.
I've got the Maplin one on the end of a Pace DTVA, and it works really well sending that via a long s-video cable to a PJ. Look for the Maplin item code WN53H, it is currently in their sale at £6.49 instead of the normal £12.99, SALE PRICE IS UNTIL SATURDAY 24th.
It takes the form of a Scart socket and plug back-to-back, with an s-video mini-din on the side.
