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.
