I use my Game Cube with a GC video based HDMI out. Previously had an HDMI to component adapter from amazon that wasn't very good. This works great, I just plugged it in and it converts the video for my CRT. Was able to send 240p/480i out to my normal CRT, and was able to put the Game Cube into 480p and send that to my multi format pvm. Might get another one for future use as this one will likely be dedicated just to my Game Cube.
