Techspansion has released VisualHub 1.3, offering support for 5:1 surround sound for Apple TV users.

VisualHub 1.3 is a powerful video conversion tool that enables Mac users to transcode content in a variety of different video formats into those supported by iTunes, the iPod, and Apple TV.

The new Apple TV 2.0 software allows for 5.1 Surround sound over HDMI and Optical outputs, so VisualHub has also been updated to support the new Apple TV feature.

Video sources with 5.1 AC3 audio will have their audio track passed directly through to the finished file, and the video will be converted for optimal playback.

VisualHub 1.31 costs $23.32 and is a free upgrade to registered customers. A free trial is also available.
