By far the best solution, in my opinion, is to buy the Elgato Turbo 264 dongle.
Here's what your workflow will be like:
You use
MacTheRipper to rip your DVDs.
Here is an AppleScript that will work with any Mac you have lying around, if you have one with some big drives attached to it. You pop in the DVD, MTR will rip it, then eject it automatically when done, so you don't really have to supervise. Otherwise, you can just do it on your normal Mac and it'll ping at you when it finishes copying the DVD.
When you have a bunch of VIDEO_TS folders, just drag and drop them into the Elgato Turbo encoder window. It'll find all of the features in each VIDEO_TS folder. Some will be dinky and only a couple seconds long, like intro videos and stuff like that. Just click the little "X" for each one to remove it from the queue. Then press <start> and it'll start ripping.
The benefits over Handbrake are immense, in my opinion, since Handbrake still does not (at least, last time I used it) handle queues simply and efficiently, making it a pain in the neck to rip DVDs of TV shows. The dongle itself is very good, immensely reducing CPU usage while enhancing speed. The presets (iPod high, iPod low, Apple TV, iPhone, etc) all work flawlessly with the appropriate devices, and iPod high works perfectly with the iPhone and Apple TV. Also, it is available to Quicktime and will automatically assist in any other H264 encodes, even those not involving the Elgato GUI, so iMovie and other conversions will also work at an increased rate with less CPU consumption.
On a Mac mini with the files stored on a PMG4 RAID-5 Array connected over 100Mbps ethernet (until
ReanimationLP sends me a new motherboard), I get anywhere from 20-30 FPS. I got 30FPS and sometimes more using the Mac mini internal drive. I have hopes that with a more powerful machine and gig-E, the encoding rate will jump, but it probably won't substantially.
Either way, it's $100 or so. It might seem a bit difficult to justify, but it depends on how much you value your time and frustration. If you have the necessary hard drive space to set up a full-time ripping/converting operation for a few days, I think the Elgato dongle will be worth purchasing. If you want to do things with more automation and freely, you can use
the aforementioned script and the one in the comments to have an AppleScript run MacTheRipper to rip the DVDs and then use a cron script with the HandBrake CLI client (that I'm not sure is currently working) to have a fully-automated system that you don't have to mess with.
Just stuff to think about.
