    I just got a new external DVD Burner for Christmas (Plextor 755uf) and decided to test out its read speed by ripping a DVD and a CD. Unfortunately the test did not go as well as I was expecting. The time to rip a 7.5GB DVD was about 50 minutes! I was using Mac the Ripper in my test. I then decided to use my internal DVD drive and it was just as slow.

    When I look at Activity Monitor while ripping a DVD the highest speed for Data written/sec is ~2.5MB/sec. This is exactly the same for both my internal and external drive. Does anyone know if something is limiting my ripping speed? I see the same cap when I try to rip a CD as well. My computer is a powerbook with the G4 processor. I'm running OSX 10.4.8.

    Any help would be appreciated. I had really hoped getting an external device would increase the speed I could rip media, but it isn't any faster.

    Conversion? Are you ripping to a specific format or something? When I rip DVDs, I convert them to AVIs. The data transfer isn't the bottleneck so much as the conversion process. :)

    Mad Jew, thanks for the suggestion, but I am just ripping the DVD to a raw format so no conversion is taking place.

    Okay, how does it compare with simply ripping data from a DVD via Finder? :)

    What interface are you using to connect the drive? If it's USB, are you certain you're not going somehow using USB 1.1 (via an old hub, for example)?

    since u tried both external and internal dvd drive, only thing i can think of is your harddisk might be slow.

    I've tried it with both USB and Firewire and both have the same problem.

    Clevin, I don't think it's the hard drive because I can transfer files to my computer from the network at 10MB+/sec.

    Thanks for the suggestiongs. Keep them coming.

    I was finally able to rip DVD video at faster than 2x speed. Plextor limits the rip speed of the DVD for some reason, but there is a way around it. If you hold the eject button for 3 seconds when no DVD is inserted it removed the rip speed limitation.

    Thanks to all who helped.
