I have a customer that has two Sony DVD Changers (777 Model) connected to a DVDO Scaler and the Scaler is connected to a 8x8 hdmi video switch via hdmi. This is all integrated into Control4 and artwork is detailed in the My Movies app in Control4. Everything works great in 2.10. Now that the system is upgraded to OS3, you can no longer start movies from the My Movies app and the artwork is extremely slow to load. If I use composer to access the dvdo and video switch I allows me to change sources and see the DVD. So, I know the drivers are working. Very strange. Is anyone having issues with DVD changers and OS3?
