HandBrake rips DVDs on this dual 3GHz Mac Pro with 5 GB of RAM at about 83 frames per second. It will spike to 90 on occasion and dip to 75 or so, too. How's your rip speed?
Update: Duh, yeah, formats help: FFmpeg encoder, 1 Mbps, MP4 video, AAC audio, 44.1 Hz and 128 kbps. I think they may be the default settings.

In what format?
My MacBook Pro (Core Duo, 2.16Ghz) does ~30fps to 2Mbps h.264 (from the hard drive), ~65fps to 2Mbps mpeg4.

Really, you do 2Mbps? Is the difference between 1 and 2 significant or discernible? I'm surprised you get 65 on a MacBook Pro. HandBrake has 12 threads and "170%" of the CPU according to Activity Monitor. I'm surprised I'm getting so little more than you.

It took me quite a long time to reach an "optimum for pretty much all the time" frame rates, and 2Mbps + 320Kbps audio seems to be the right fit for movies. At 2mbps I find it hard to tell the difference between h.264 and a DVD, mpeg4 and DVD was a little easier but not much. 1Mbps I found easy to spot. There are far more artefacts, especially in darker colours/lighting.
As to the speed differences - I'm also kind of surprised. Do you rip to the hard drive first and then use HandBrake, or do you go straight from the DVD?
I pretty much exclusively encode to h.264 now, it's fast enough.

Straight from the DVD. I didn't see much value spending 30 minutes copying to the hard disk if I can spend 30 minutes ripping from the DVD (just under three hours of content).

If I was encoding these for more than just one viewing, I might care more about the quality. Even still, I've bumped it to 2 Mbps for the disc I'm ripping now and framerates are around 80 FPS.

Right - I rip to the hard drive first using MacTheRipper, mostly because I sleep in the same room as the MacBook Pro, and that's usually when it does it's encoding thing. It typically only takes 20-25 minutes to rip a dual layer DVD, and then it's much quieter. I wonder how much of a difference it would make.
I just noticed you said it was using 170% - I see similar %-ages here, which seems to imply it's not using all 4 cores, or certainly not to their full potential.

Right. And 65/83 is pretty close to 2.16/3.0. Bummer.

Hi Erik,
I'm a Handbrake dummy and just want someone to give me simple numbers to get the best quality. I'm on MacBook Pro (2Ghz 2Gb ram). I rip from the dvd, change the Codec setting to H.264 and the Video Quality to 6000 kbps. This gets a nice picture but I don't know for sure if I'm going about it all correctly.
I don't mind what file size I end up with, I just want to get the best picture quality.
Any suggestions would be terrific.
Thanks.

I'm not into the tech #'s, just wondered what the average 'real time' rip speeds are. Let's say a 2 hr DVD, presets for Apple TV. I'm a simple guy.
I've been having pretty long rip times on my iMac G5 PPC, that's maxed out in RAM. I haven't tried it on my MacBook yet.
I do agree that copying the files over first and then letting Handbrake do it's thing is easier, and more quiet and saves on your disc drive spinning and stopping and spinning, etc..
Would appreciate any info.
John
