I've now managed to get the pix_snap2tex images to overlay without any noise around the edges...god knows how, I fiddled with so much stuff!
But I still can't get the 'snaps' to match the size and shape of the live feed. If square they tend to only sit in the middle. If I make them rectangular this takes is slightly better as they mask the whole live feed, but they still appear distorted as though the rectangle has been squashed vertically. And when I make the Gem win full screen, then the snaps only take up the top half of the screen.
All I want is the 'snaps' to exactly match in size and overlay the live feed. Surely this shouldn't be as hard as I'm finding it!

Following on from my question earlier, I figured I would annotate my patch and attach it so people can understand it a bit better:
Basically, when this patch is finished I will be outputting it via a digital projector, so it will need to be at least 720x576 pixels res (PAL tv res).
Patch Key:
Yellow area: Live feed from webcam
Red area: 500ms Snapshots from webcam feed
Green are: this is where the background movie will go that the live feed will be keyed over.
I know that everything here is not refined yet, and that the chroma-key is not set up yet, but this is basically how my patch will probably be set up. I will be overlaying a derivative of the red area feed over the green area feed. But for some reason, I cannot get the pix_snap2tex feed to match the res/proportions of the live webcam feed. The snapshots tend to appear a lot smaller, with kind of garbled screenshot data/noise around the edges.
If anyone could tell me what I'm doing wrong, you'd relieve me of much frustration!
