Now that HD DVD is dead, Blu-ray is poised to take over as the consumer home-video format of choice. It offers high-definition video and high-resolution audio, providing a superior viewing experience to DVD, although you need a modern home theater to take advantage of it. Like every new format, Blu-ray comes with a whole host of new terminology, like 1080p, Blu-ray profiles, and onboard decoding. It can be overwhelming, but remember that Blu-ray is basically just like DVD: pop in the disc, then sit back and watch movies in high-def.

Blu-ray vs. DVD

In most ways, Blu-ray is fairly similar to DVD. The players look the same, the discs look the same, and even the disc menus are similar. So why pay more?

Blu-ray brings three major improvements over DVD: better image quality, better sound quality, and more special features. All three are made possible by the larger storage capacity of Blu-ray, which is capable of storing 50GB of information on a single Blu-ray Disc, compared with DVDs, which can hold about 8GB.
What’s better about Blu-ray?

Image quality: Superior resolution is a big part of what makes Blu-ray look great. In layman’s terms, this means you’ll see a more detailed image: more clearly defined strands of hair, wrinkles in clothing, etc. The technical difference is that Blu-ray’s maximum resolution is 1,920×1,080 (1080p), while DVD is limited to 720×480 (480p). Beyond resolution, Blu-ray also uses better video-compression methods, resulting in more contrast and richer colors. If you like the way HD from your cable or satellite provider looks, Blu-ray looks even better. It’s the highest-quality video format available today, and in some ways it surpasses the picture quality of your local movie theater, especially when shown on a good-performing HDTV or projector.

Audio quality: Audio quality is also improved. New high-resolution soundtrack formats, such as Dolby TrueHD and DTS-HD Master Audio, are essentially identical to the studio master, so you’ll be hearing things exactly as the director and audio engineers intended.

Special features: Blu-ray also has additional special features over DVD. The most basic innovation is the pop-up menu, which allows you to access the menu functions while the movie continues playing. Other innovations include picture-in-picture video commentary and the ability to download new content right from your Blu-ray player, although your player needs to have the right Blu-ray profile to access these features. In our opinion, the special features on Blu-ray have mostly been underwhelming and aren’t a good reason to upgrade.

What’s worse about Blu-ray?

Cost: Blu-ray’s main drawback is cost. Prices for players are still generally over $200 and movies cost about $25. While the one-time cost of a player isn’t that bad, the cost of building up a new Blu-ray library really adds up. At least it’s possible to pick and choose which movies you “buy Blu,” since every Blu-ray player can also play standard DVDs.

Load times: When Blu-ray first came out, load times were unbearable; it could take more than 3 minutes to load a movie. Since then, players have gotten much faster, but they still don’t compare with the speed of loading a DVD. While simple Blu-ray movies can load in about 20 seconds on a good Blu-ray player, movies with complex menus still take close to a minute and a half to get to the actual movie, regardless of the player.

Portability: Lastly, if you start buying Blu-ray movies, you may get frustrated that your new movies won’t work in places where you only have a standard DVD player. For example, if your bedroom only has a DVD player, you won’t be able to watch the second half of your new Blu-ray Disc from the comfort of your bed. Or if you have a car with a built-in DVD player, your new Blu-ray Discs won’t work there, either.
