Hi simon,

I think my first port of call will be to image the backup machine and restore that onto the main to see whether its something i've accidentally changed in the software/os, but failing that a second computer will be on the cards methinks.

Your point about the resolution of the image is a very valid one, and indeed quite obvious when i think about it. Projector's native res is xga so i've changed it to something close to that, at least (1024x1089 is the closest photoshop will allow without screwing up the aspect)

I'm only blending outputs 1 & 2 and this suspected troublesome still is only used on the third output.

Good to know about the bottom bar not being accurate when using stills. I did notice that if i loaded a movie into another layer whilst the png was in layer 1 then the meter dropped to something sensible.

I'll report back on my findings.

Thanks for all your help
