Cheers, but I'm avoiding everyones helpers and scripts and stuff (for now) until I get my head around the technicalities of the renderer and nodes a bit better than I have so far.  If I downlod the BB stuff I'm worried I'll get idle and won't bother trying to learn the stuff I need to.  I'm still trying to get it do do Anamorphic stuff properly, it's probably dead easy to do with a very obvious way to do, it but I've not figured it out, so to me, that's a problem I have to deal with.

Still, I only have a stab at it now and then, so that's my excuse for still figuring it all out :-D
