Suddenly I'm unable to create DVD disk images with Disk Utility.
I've done it before but now Disk Utility reads from the DVD for a long
time, usually getting well past halfway through and then stops with the
message "Unable to create ABC.dmg - input/output Error."

I'm running OS X 10.11.4. I used a Memorex lens cleaner. I've
used at least three DVDs, some multiple times, with the above results
every time.

Any ideas?

What type of DVD are you reading from? Is it a commercial TV/Movie DVD,
if so it is likely copy protected.

Have you checked the condition of the DVD your are trying to copy?
Scratche and fingerprints can cause problems when copying.

You are way more advanced than the rest of us.

Well, some of us just have a lot of clout with Apple.

You're right. It's 10.4.11.

How much free space available on your hard drive?
Enough for a DVD plus overhead?
