I use Handbrake to rip DVDs for my iPhone and Apple TV (and previously for my Treo 650, at much lower quality). It's excellent, but takes a long time, and slows down the whole system while compressing. My PowerBook G4 wasn't powerful enough to do H.264 compression in reasonable time, so I got into the habit of ripping the DVDs on the Mac with Mac The Ripper, copying them to the server, converting on the server, and copying back down to the iPhone through iTunes on the laptop. Transferring a full DVD via gigabit Ethernet takes under 10 minutes, which is why we have 3 1/2 gigabit Ethernet switches (8-port, a pair of 5-ports, and the 3 ports built into the Time Capsule) in a 3 1/2 person (2 grown-ups, a 5-year-old, and the cat) home.

Since then I've upgraded the laptop and replaced the server, so they're now both 2.4GHz Core Duos, but I still prefer to avoid the load on my personal machine -- especially now that we have an Apple TV, which likes large high-quality video files. The MacBook Pro runs HandBrake.app (Mac GUI), while the server runs HandBrakeCLI (Linux).

HandBrakeCLI is designed to convert individual files and is awkward for converting whole DVDs. Fortunately I found MediaForkCLI-batch.sh, a wrapper which is good at converting all the real titles from one or more DVDs; it automatically ignores short titles such as previews, and titles that have already been transcoded. Unfortunately MediaForkCLI-batch.sh is languishing, and hasn't been updated for HandBrake v0.92, but it was straightforward to update it to the new syntax.

In the process I made some changes and added an alternate version with different settings optimized for our Apple TV. On the Linux box (named inspector), the scripts are ~/bin/appletv.sh & ~/bin/iphone.sh. I put newly ripped files into ~/tivo-inspector/input/ on inspector, and these scripts rip whatever they find there, generating files in ~/tivo-inspector/output/.

On the MacBook Pro, I keep video files in ~/tivo, and ~/tivo/tivo-inspector is a symbolic link to tivo-inspector on inspector, the server -- mounted via AFP. This makes it easy to move files back and forth.

For convenience, I have a couple aliases on the MacBook Pro which log into the Linux machine, start a screen session, and run the appropriate script. This means that if I disconnect the laptop, I can later ssh back into the server and use screen -DR to reconnect to my running conversion session. When the conversion is done, the aliases open the remote folder in the Finder. I move the files back up out of input & output, drop them onto iTunes, and then either Sync the Apple TV (which gets copies of my whole iTunes Library), or sync them to the iPhone.

The scripts are appletv.sh & iphone.sh.

If you use these scripts, you should carefully review the encoding settings. In particular, I encode Apple TV audio to AAC stereo, because our Apple TV is connected to a pair of stereo speakers with a subwoofer; they cannot handle Dolby Pro Logic, which is better for most TVs.

You will also have to update paths in the scripts -- to the input and output directories, and to HandBrakeCLI itself -- to make them work on your own system.

Here are the aliases in sh/bash format; change the equal signs to spaces for csh/tcsh:

alias appletv="ssh -t inspectore time screen bin/appletv.sh; open ~/tivo/tivo-inspector"
alias  iphone="ssh -t inspectore time screen bin/iphone.sh;  open ~/tivo/tivo-inspector"
