One possible solution for ripping stubborn discs

While writing up this week’s Watch It selection (The Stunt Man), I was rewatching the movie on my TV, and wanted to switch over to the computer. I own a many-years-old DVD version, so I popped it into my iMac, fired up HandBrake and set to ripping it. But I got nothing—HandBrake ripped a 4KB file, then claimed it was done. Not a good start.

A glance at HandBrake’s activity window showed this error:

libdvdread: CHECK_VALUE failed in ifo_read -- error message

Searching on that error message pointed to an error in dvdnav, and some suggested ways of working around it, including installing a patched version. There were also other errors, and searching on those indicated something about the copy protection was causing a read error with the disc.

I also tried RipIt’s built-in rip-and-compress, but it also failed. After mucking about with those two apps, and nearly every other video-related app I own, here’s how I finally managed to rip my legally-purchased version of The Stunt Man:

  1. Used RipIt to copy the DVD to my hard drive. (No settings to worry about here at all.)
  2. Used MakeMKV to make an MKV from the ripped file. I pointed it at the folder from step one, and clicked the Make MVK button. The end result was a number of files, with the longest one being the movie itself.
  3. Used HandBrake to convert the longest MKV file to an m4v file. I just left the settings at the default (high quality), and the end result was a nice quality 1.9GB movie (down from a 7GB MKV file) that plays on all my devices.

I’m posting this here mainly so I remember what I did, but perhaps it’ll help with your stubborn discs as well.

  1. I wonder if the ‘–no-dvdnav’ argument in handbrake would have helped?

    Occasionally it makes handbrakecli work with certain disks.
