aTV Flash (black) from FireCore is a hugely popular software package that adds a ton of functionality to your Apple TV. With aTV Flash (black) you’ll be able to stream media directly from your Mac or PC and play a variety of popular file formats, like MKV, AVI, MP4 and more. Of course, to run this software you do need to jailbreak your Apple TV, so here’s our general disclaimer about jailbreaking Apple devices: it will void your warranty, so if you break your Apple TV, Apple doesn’t have to fix it or replace it. With that out of the way, let me tell you that you can now get aTV Flash (black) for only $30 $19.99. It is available here for the 1st and 2nd generation Apple TVs.
