FireCore's Infuse app is already handy for iOS users who want to play less common video formats; with the 1.3 release, it might prove vital. The new version brings AirPlay, letting viewers push any of 14 video codecs to their Apple TV. Transfers should also be simple now that users can use a web browser or FTP client to copy videos over WiFi. There's even a social aspect to 1.3 -- Infuse now sends play counts and ratings to trakt.tv, and users can advertise what they're watching through Facebook and Twitter. If VLC for iOS isn't quite your cup of tea, you can spend $5 at the App Store to try FireCore's take on mobile movie playback.
