Using Handbrake to rip some DVDs - the kids are starting to "play" with my DVDs so I want some backup - and the 2.66 quad Mac Pro will rip a DVD in 40-45 minutes. Great.

Figured I'd crank up the ol' 2.5 dual G5. It'll take 3-4 hours. Woah.

The 1.83 (dual) MacBook Pro also takes over three hours.

Not only is the Mac Pro absolutely rocking for performance, it doesn't get noticeably louder either. Whereas the other two are pumping fans at full throttle and the MBP's DVD drive is also noisy as heck, for some reason (it's quiet during normal playback).

Mac Pro: amazing!

Ever since upgrading to X.5, I've had almost daily kernel panic (window shade) problems. Any ideas? Thought there was a firmware update recently but SWU say's I'm up to date. Short of reinstall other options?

unsanity's window shade is obviously the culprit… uninstall all the haxies you could have there.

I don't have Window Shade. I was referring to the kernel panic you get when the grey screen descends in front of your eyes. It also happens as a "won't wake from sleep" type occurrence. thanks

That is amazing. It takes me 24+ hours. I shouldn't be doing it in the first place though.

MTR rips a DVD on my G5 in about 30 minutes.

The real test is seeing how long it takes to make h.264 MPEG4 movies from those DVDs. MTR doesn't do that, but HB can.

24 hours? Wow. That's extreme - I don't remember how long my pb takes, but it's nowhere near that long. More RAM will help you I think. Of course, MTR is not re-encoding the video.

MTR is not Handbrake - they do completely different things. MTR you end up with a copy of the DVD (which is certainly nice to have). Handbrake you end up with a (roughly) 2GB file with the movie, suitable for streaming - to AppleTV for example. Handbrake really cranks the CPUs :-)

I could probably set up MTR or Handbrake to rip a DVD in a few minutes on my MacPro if I set the quality to crap.

My MBP (2.0 core duo) rips a DVD in 45 minutes too.

Again, MTR just copies the DVD. It does nothing to the quality.

I have a dual 1 Ghz MDD and it always takes 14-15 minutes to rip a commercial DVD. How can the current machines take longer? Is MTR optimized for the G4?

Good you pointed it out again. Obviously there seems to be quite some misunderstanding here.

MTR basically only benchmarks the performance of your DVD drive. All it does (apart from decryption) is read the VOB files and write them to disk. The time which is required to do that is determined by the transfer rate of your DVD drive. That's why Big Mac's G5 appears to be equally 'fast'.

HB on the other hand recompresses the data. If you for example chose h.264 encoding that is basically a CPU limited task. An eight core MP will completely slaughter an older Mac at that.

I assumed it's a dual-processor 2.5 instead of the dual-core PowerMac G5. I haven't tried HB with Leopard, but it took around 4 hours on my DP 2.0Ghz G5 in h.264 coding under Tiger. It topped at ~30 fps while my work 2.0Ghz Mac Pro did ~100 fps.

That explains it. MTR rips it while HB transcodes it...
