The company that invented the DVR is re-inventing it. ReplayTV has left the living room to TiVo, last-generation ReplayTV recorders, and cable and satellite providers that offer DVRs as a premium feature.

Let's recap: Al Gore created the Internet, and, on the seventh day, he rested. Immediately, entrepreneurs began selling pornography, and the World Wide Web had a purpose. Before long, people started posting videos of their dogs belching the national anthem, and, yet, an entertainment-hungry globe craved more. A bunch of other stuff happened, and now Apple has been selling songs, music videos, TV episodes, and feature-length movies via the iTunes Store,embedded in the free iTunes application for Mac and PC. While digital-rights management protects purchased video and audio (although this may be changing), you can enjoy it at the computer and upload it to various iPod portable devices. Still, a growing contingent yearns to relocate its premium content to the comfort of the living room with due ease and elegance.

Over in the June issue of the Home Theater print magazine, I wrote about the wonders of the Microsoft Windows Vista Ultimate, the most highly-featured version of their new operating system, and how its many features make it a great match for the latest HTPCs. Which begs the question, "What are home theater PCs wearing in the Vista age?" And to help answer my query, Intel sent over a test machine custom-built around their Intel Core 2 Duo processor, specifically designed for audio/video applications, running Windows Vista Ultimate.

We're down with entertainment PCs here at Home Theater. For those of you who are ready to share the joy, there are basically two ways to join the party. For the hands-on approach, we've written about specific best-of-the-best audio and video cards and other devices that you can plug into your own custom-built box. But, for some readers, personal success has brought with it the notion of luxury. Companies like HP are only too happy to remove the guesswork from the equation and pre-assemble a bundle for you, which you can purchase with one phone call or just a few clicks online. Their Pavilion Media Center TV m7580n HTPC is just such a system.

The big news in 2006 has been the emergence of two new high-def DVD formats—Blu-ray and HD DVD. With greater storage capacity than a traditional DVD, we can now get higher-quality audio and video on the small screen. Depending on the compression used, each release can contain a whole slew of extras—or you can fit entire seasons of television shows, in SD, on one disc. Now, with the introduction of some internal drives for the home computer, you can back up vast amounts of information with a single disc. My personal iTunes music library, which contains the majority of my CDs, encoded as AAC files at 192 kilobits per second (stereo), could almost all fit on one Blu-ray disc. That's three-and-a-half months of continuous music. Add the ability to play Blu-ray titles, and it's the perfect time to move that home computer into the home theater for some high-def goodness. Before you get too excited and run out to buy a new drive, there are a few things that you need to consider first.

A while back, we Home Theater drones were all on Macs, and life was good. Then, one day, the powers that be told us that the bulk of us were switching to PC, and that was that. I had a few annoying differences to work through, but I eventually forgot my first real computer. And then the Mac mini showed up for review in its pretty white cardboard box, and it reminded me of the experience of bumping into a friend from the old neighborhood: familiar, sure, but with a lot of catching up to do.
