I have heard that developers have access to a program that allows them to take screenshots from the 360 strait from the buffer. I was wondering if any one knew where to get this program since it does not have a name and also will it work on a off the shelf xbox.

The program would be part of the XDK which is not distributed and M$ only gives it to licensed developers. You will never see it until we get a full hack and an XDK is leaked. We had OpenXDK and a few other legal apps to take screenshots on XBOX1, but those came long after the official XDK was released. And most likely even when it is leaked and can be used it will be far too much trouble to obtain and setup for what you want to do with it.

Much easier option is to buy a capture card or capturing device of some sort.
