I actually first heard about the aTV Flash a month or so ago but decided not to write about it because it seemed a little fishy to me. But, now that some of the bigger blogs out there decided to write about it I figured it must actually work.
The idea behind the aTV Flash is very simple, it is basically just a USB flash drive preloaded with some software that once plugged into the Apple TV it automatically hacks the Apple TV to add multiple codec support, the Couch Surfer browser, SSH access, etc.
The aTV Flash is compatible with all Apple TV’s including the old software and Take Two and the makers of the aTV Flash offer free updates for a year. It is a little bit expensive, coming in at $59.95 it isn’t exactly cheap, especially since all of these hacks can be done by yourself for free but the convenience may be worth the cost.
