Hi. I just ended up buying a Elgato Cam Link because of this thread. I have a Blackmagic Intensity Pro 4k and it does not play nice with the OSSC. With the Sega Dreamcast VGA it works to an extent in 480p pass through. The NTSC Sega Saturn via SCART I get a rolling picture in 2x and blank for everything else. All modes with the Saturn work with my TV.
