Well, I did a clean install of Leopard on my PowerMac G5 and most of my main apps are working with minimal issues. Only BIG app that I really need to be working is EyeTV 2.5 and my two tuners (EyeTV 500 and EyeTV Hybrid). It starts up okay, reads my old EyeTV archive okay (I also tried with a new clean archive), allows me to scan for channels (so it can see and talk to the tuners), and playback old recordings. What it doesn't do is allow me to open a live window or record anything. It gives and error -5000 when it first starts and tries to open the live window. EYeTV app also won't quit without a force quit. Any ideas?
