Rip DVDs for Playback on Your iPhone, PSP, Xbox 360, PS3, AppleTV, or Any H.264-Enabled Player
It’s hard to believe in the iTunes era of blink-and-you-miss-them CD rips, but in the mid-90s, ripping a CD was a time-consuming process, fraught with peril. Ripping a single disc to 128kbps MP3 could take 8 hours on a 200MHz Pentium! Fast forward a decade, with faster hardware and better software and CD ripping is so mainstream your mom does it.
Ripping DVDs and transcoding the video stored within into more efficient formats involves an order of magnitude more scary math than ripping audio CDs. A machine that will rip the latest Miley Cyrus CD in moments could take hours to extract and convert your copy of AVP to an iPod-friendly format. However, with the right software, a quad-core equipped PC, and a little know-how, you can cut your disc rip time from hours to 20 or 30 minutes. There are still plenty of tricks and traps for first-time rippers, but we’ll show you the basics, then walk you through the secrets of ripping power users everywhere.
However, the first thing you need to decide is simple: what player are you ripping your discs for? Are you ripping for a portable player, like the PSP or iPhone? Would you rather stream to device in your living room, like the Xbox 360, PS3, or Popcorn Hour? Are you simply interested in making an archival-quality DVD rips, in case you lose your collection? More likely, you’re probably looking for a combination of all three of these things. We’ll show you how to rip your DVD to a file suitable for streaming that consumes a fraction of the disk space of a DVD but maintains full video and audio quality. Then you can take that file, and convert it for whatever other devices you might have, like a PSP or an iPod. For the purposes of this story, we're going to focus on DVD rips. Getting ahold of unencrypted high-defintion video legally is still pretty tricky. We'll update with Blu-ray ripping info as ripping Blu-ray gets easier.
With the preliminaries out of the way, let’s get started.
Determining Your Target Player
There are several different factors that determine the compatibility of your ripped video files. The resolution of the video, the video and audio codecs, the container format used, and even more esoteric things like the framerate can affect whether your video will work on your device of choice. If you just rip discs as you need the content and then delete files afterward, simply rip to the target of choice. However, if you want to build an archive of ripped movies, we recommend that you use open, widely-supported codecs and containers at the native resolution of the DVD, and then transcode the files as you need them to lower resolutions and bitrates. Naturally, we’ll show you how to do both.

Your player selection also impacts your choices when it comes to audio tracks and subtitle support. While the most common container formats, mp4 and mkv, support multiple track and subtitle streams in one file, few players will work with multiple audio tracks, and an even smaller subset will work with subtitles. That means you need to rip a single audio track—typically the main movie’s English soundtrack—and burn the subtitles into the video, rather than leave them as separate streams inside the container.
Bitrate is a little trickier. Most hardware players will handle whatever bitrate you select, especially if they're designed for high-definition playback. Both consoles and the AppleTV support high-definintion files, so they're more than capable of playing DVD-resolution video at whatever bitrate you choose. However, the higher a bitrate you choose, the larger the file will be. From our testing, we found the sweet spot for most movies to be around 2000kbps average, but we cranked it up to 2500kbps for movies with a lot of action. If your hardware supports high-profile H.264 (Xbox 360, PS3, and the Apple TV do, but many portable players don't), you can get away with a lower bitrate. With 1.5TB hard drives available for about $180 now, we'd rather rip at a too-high bitrate to ensure maximum quality video than save a few hundred MB of disk space.

We typically recommend ripping to the MP4 container, it’s widely supported on both streaming devices and portables. Furthermore, the tools for manipulating the streams within the file are established and easy to use, which makes it easy to transcode your video to a less supported format for a specific player.
A Word About Subtitles
Typically, DVDs include multiple subtitle streams that serve different purposes. Nearly every DVD has some English subtitles, even non-foreign language movies. It’s important that you understand the difference between subtitles and closed captions. Subtitles are simply the dialog from the movie written across the bottom of the screen. Closed captions include subtitles, but they also include audio cues that help people with impaired hearing enjoy the movie fully.

While closed captions are present on almost every disc, many English-language movies also use subtitles to show what a character speaking a foreign language is saying. On some discs, these subtitles will be hidden in a separate stream, while in others, they’ll be mixed in with the closed-captions, but marked so that the DVD player only shows the proper captions. Regardless, it’s crucial that you get the proper subtitles for all the films you rip. Otherwise, you’ll never know what Jabba or Greedo are saying in Star Wars, and watching a long expository scene in another language without the benefit of subtitles sucks.
In practice, the first English subtitle track is typically the one that includes subtitles and forced or otherwise, while the second subtitle track is the one that includes closed captions.
