Eachine EV800 goggle DVR mod for live and recorded video

Modified the Eachine EV800 goggles to not only record my flights to an attached DVR, but to also allow playback to the goggles. I had to further modify the connection to put a simple switch in to continue using the goggles for flying as there was too much of a frame rate drop and increased latency when using the DVR's video feed while recording. With the switch in place, I can now select to review my footage from the DVR or use the live video directly from the receiver. Hope this video is clear enough to help others who want to make this mod. Leave questions or requests in the comments.
