Hi! I just discovered this project and I want to try it out. I have an Nvidia Shield that I use to playback movies to my TV. The shield is set to automatically change the TV's refresh rate to 24hz when a 24fps movie is played. While reading through the diy guide I found this: "When video capture is turned on you are limited to 50/60hz due to technical restrictions, a solution for this is to add a remote controlled power brick (KaKu for the dutch users) and put the HDMI->Composite converter in that. Make sure you get an powered HDMI->Composite converter and not the passive one that is powered by the HDMI signal ! So if you want to use video capture just toggle it on via remote and leave it off when needing 24p playback." Does this mean that the ambient light can't used with 24p playback?
