I have the same problem. I have a jailbroken iOS 4.3 atv, airplay enabled and I can ssh into the device and install nitoTV. The firecore installer can not find my atv. I have tried the windows and mac installers on two laptops.
I just tried it via logmein and it found the ATV on the first try. I got an installation error but I am doing this remotely so I do not have a lot of info.
Happy I did the JB right though. :) :[
Actually it see's both my ATV's and I only JB one of them I think so it see the ATV even if it is not JB.
how come theres not more people from firecore to help us with our problems, i am having the same problem... apple tv could not be found... with all the steps rechecked over and over, homesharing is on and so is airplay, also downloading the program several times. i start the installer and all it ever says is apple tv could not be found. please can someone help us with this!
