I dont know if you ever watch movies on your Amiga, but DivX / XviD playback must only be possible with PPC version of players? I doubt the 060@66 is upto the job?
PPC versions of Emulators such as Gameboy, GBA, Megadrive(Genesis), Snes etc. must all be better? If you are a retrogamer this must be good?
As for the switching... can you not get a program to switch off one of the outputs and then the Monitor will switch for you?( If you have a dual input monitor like me)
