I found a work around, although it cost me an extra $22, but it does seem to solve the issue of my Canon Vixia HF R800 seeing the PiVideo HD as a 480p device. It’s called the “FUERAN HDMI Pass-Through EDID Emulator for use with Video splitters, Switches and Extenders (fit-Headless) 1920X1080@59hz”. I need to do more extensive testing but plugging it in between my camcorder and the PiCapture HD 1 has successfully locked the PiCapture HD 1 into Mode 1 1080p. And the camcorder is outputting 1080p signal. So yay!
