The 3D TV landscape got a whole lot more complicated at this year's CES—and it was already plenty complicated before the show! In addition to displays that use active-shutter glasses, we now have some that use passive-polarized glasses and a few flat panels that use no glasses at all. In particular, I've been seeing quite a few blogs about glasses-free 3D, such as this one by Grant Clauser for CEPro and this one by Stewart Wolpin for TWICE. Both commentators reject the current viability of glasses-free 3D, which is more formally known as auto-stereoscopic, and with good reason—it looks lousy, and it confuses the 3D market considerably.

How do I watch content on my DVR when I'm away from home? How often should I clean my projector's air filter? Why are optical-cable prices so wide ranging?

Theta Digital is one of the most venerable companies in high-end audio, offering many well-regarded products over 25 years. Even more impressive, many of those products are still available after years of upgrades and refinements. Take, for example, the Casablanca preamp/processor, which was first introduced 15 years ago. Its latest incarnation, the Casablanca III HD, adds HDMI 1.4 I/O and the ability to decode Dolby TrueHD and DTS-HD Master Audio.

The long-anticipated debut of 3net, a 24/7 3D network co-founded by Discovery Communications, Sony, and Imax, is set for Sunday, February 13, 2011, at 8:00 PM ET, when it will be carried on DirecTV's channel 107. Those who tune in that evening will see China Revealed, followed by Into the Deep, which took the Imax 3D camera underwater for the first time, and Forgotten Planet, a look at the "strangest places on Earth."
