Hello,
I have tried both the Chrome extension and the program. For the Chrome extension, it founds my FireTV. I was able to fling my tab to the FireTV, but some media sites won't work correctly. For example, for youtube, when you open a video, it will says that video can't be play in FireTV. To get around this, start the youtube video on your computer, then fling the tab to FireTV and it will work. I don't know why but that is how I make it work. It works fine for a few hours then it crashed and I have not been able to fling my Chrome tab anymore.
For the Window program, it found my FireTV and I was able to connect using my IP address. However, when i click the "Mirror" button, the app seems to launch and a black screen show up. If I play a video file, or go online to a website that has videos, sound will play through the FireTV but no picture show up, still only a black screen. I have tried this both on my desktop and my laptop. Both running window 7 64 bit up to date and got the exact same result.
Just a question, since your program does not work for my computers. What exactly does it suppose to do? Does it mirror the entire screen just like a 2nd monitor? I will be happy to provide any help or troubleshoot crash log. The app is very promising but needs a lot of work and tweak. Good job.
