Media extenders such as the Pegasus Cynalynx are popping up left and right these days. The most famous of them, the Apple TV, is geared toward the iTunes-loyal masses, whereas Netgear's Digital Entertainer HD EVA8000 seeks to appease folks with a varied media library who need versatility from their box. Although the former has serious limitations (iTunes-only) and the latter is saddled with issues (it likes to crash . . . a lot), both are worth looking into. Unfortunately, the same cannot be said for the Pegasus Cynalynx. On paper, the Cynalynx boasts an impressive feature set. It streams DVDs that are playing on your PC, as well as your computer's audio and video files, to your television. It can be used to browse the Internet and view photos, too. And unlike Apple TV and Netgear's device, it has its own built-in wireless router. There's only one problem: We could hardly get any of these features to work.
