Here was the response I got from contacting via email...no real info, as expected.

Dear DukieDrew,

Thank you for your e-mail to Delta Air Lines.

The In-Flight Entertainment systems contribute to the enjoyment of a
flight, and we share your disappointment that there was a problem. We
want flying on Delta to be pleasant and regret any role we played which
caused your travel experience to be otherwise.

Again, thank you for writing. Please accept our apology for the
circumstances you described. Your comments are appreciated since this is
one of the best ways we have of knowing which areas need additional
attention. We hope you will continue to make Delta your airline of
choice.

Sincerely,

Mark
Manager
Customer Care
