With Android, everything worked as advertised, though the device took a while to catalog the multimedia files before I could play them.

For PCs and Macs, the Optical Smart Hub supports playback in whatever application serves as a DLNA client, such as Windows Media Player. However, although the Optical Smart Hub showed up in Windows Media Player initially, when I attempted to access music and video it disappeared or gave me an access error.

The Samsung Optical Smart Hub is an odd duck, suitable for the limited scenario where you want a Wi-Fi router, NAS-like storage, and media streaming for mobile devices on an independent wireless network. Or rather, it would be suitable if the software were up to snuff. Once Samsung fixes the software--and if the company gives the device the ability to act as a shared resource on an existing network--this gadget's appeal will broaden tremendously, giving you a way to enjoy your collection of movies and other disc-based media via your smartphone or tablet.
