Snared the video you want with aTV Flash (black), but still foraging for subtitles the old way? Version 1.6 of the $29.95 package will now hunt them down from OpenSubtitles.org and download 'em directly to your jailbroken Apple TV 2nd-gen. In addition, Firecore's undermining software now has more codecs and languages, smoother video playback, better networking and numerous refinements and bug fixes. Existing clients will score the upgrade gratis, and new orders won't pay for Apple TV 3rd-gen functionality when it comes out. If you want to say no mas to badly dubbed films, roll to the source for more details.
