I was told that if one PiP is active it shows at half normal frame rate. If more than one PiP is active the frame rate(s) are even slower. Useless. I was also told that, yes, the size and position of PiP's can be changed, but my request about the size being up to a quarter screen for two of the PiP's could not be met. The resize option does not go up that big. I am looking for an outboard box to provide two side-by-side full frame images from two sources for my projector or any TV.
