I think there may be a simpler way of doing it than messing with eyefi stuff. When a picture is taken, file manager can see that there is a new file in /DCIM/100EOS5D and that the .CTG file in /DCIM/EOSMISC has changed size. File manager also can see a new .MLV file without a reboot. Does anyone know what's done when writing an MLV file that makes it show up in file manager without rebooting?
