That's generally caused by a combination of a cheap/bad high speed DVD-ROM drive and/or bad ripping software/options settings. What seems to happen is the ripping software is running a marginal drive/dvd at full speed and disabling the drive retry on error. Combined with all the soft ways these drives fail it results in a bad rip.
This used to happen to me a few years ago, and it was overwhelmingly just a sign of a marginal drive. For about 10 years, I was replacing drives about once a year. It doesn't happen as frequently since I started using bluray drives (usually LG) to rip DVDs and a piece of software designed for "piracy".
Anyway, two software things to try, are lower the ripping speed to 1x-2x, and make sure to leave the drive retry on bad sectors enabled. Most decent ripping software will have options to control the error correction/retry logic. The problem is some copy protection schemes leave bad sectors on the disks, and this will hang a lot of the "honest" ripping software that doesn't know how to deal with it.
If the OP has been using a low-quality DVD drive, I recommend using an Apple SuperDrive, since he mentioned Apple.
They may not have all the latest whiz-bang features, but they are rock solid, and are USB powered. I have two at home, and use them to rip DVDs, and have never had a failure in I don't know how many years.
New they run $79 from Apple. Or you can get a used one off shopgoodwill.com usually for around $15.
