I just installed ATV Flash (black) 1.2 on my PC running Windows Vista. I JB’d my Atv which runs 4.4.4. Everything appears to have installed correctly on the Atv, and I followed the instructions (Home Sharing is on, etc) but none of my AVI files show on screen – the whole reason I bought this program is so I could access the AVIs via Atv and iTunes. The avi files don’t show on Atv or in iTunes on my PC.
It might be relevant to mention that I also have installed on my Atv Nito, XBMC and Plex (then bought Atv because I couldn’t access my AVI files on any of those, either).
