How well do the new compression schemes from Dolby and DTS stack up against uncompressed audio? We buff up our golden ears to audition and compare the latest Blu-ray audio codecs, in the design labs that developed them.

Compared to DVD, the tremendous increase in storage capacity of the Blu-ray disc format, necessary to carry the increased high definition video data payload, also provides for expanded audio options, including the ability to carry so-called lossless audio formats such as Dolby TrueHD and DTS-HD Master Audio.

When you turn off your flat-panel TV, it becomes a black hole in the wall. Here’s how to hide it away when you’re not watching.

My friend Steve just bought a large flat-panel TV and mounted it to the wall. He assumed his wife would love the sleek look, but she’s not happy with the way the TV becomes a “piece of black glass that’s just hanging there” when it’s not in use. It seems like she wishes the TV would just go away when they’re not watching it. Luckily for Steve, it doesn’t take any magic at all to make that happen.

You want me to buy more speakers? Yeah, I get that. To be honest, that was my first thought when I heard about height speakers. Just a gimmick, right?

Which is better, or more precisely, which isn't worse

It's not that I hated Time Warner Cable. In fact, in a lot of ways I kind of liked them. For several years, I had the Scientific Atlanta 8000HD DVR box, which, after many updates, was a pretty decent piece of equipment. Then, after my second one died (as hard-drive based equipment is bound to do), they gave me the 8300HDC. This is the worst consumer electronics product I've ever used, and my days with TWC were numbered. And along came AT&T.
