Thank you for contacting Redbox Customer Care. We're sorry that the Blu ray you rented did not have the audio that you like. Please understand that to keep rental cost low, Redbox has made agreements with studios to provide DolbyDigital 5.1 audio on some of our Blu ray discs. We just ask that going forward you keep this in mind, so not all the Blu ray discs you rent will have the audio you are asking for.
We understand how disappointing it is when you're unable to rent something in the format you want Mike. As a one time courtesy, I’ve issued you a rental credit, good for free, one-day rental of any DVD or Blu-ray Disc of your choice. The credit is valid for 30 days from today's date.
• To use a credit at a box: at checkout, touch the USE CREDITS button. Then swipe a payment card associated with your redbox.com account, confirm your credits and finish checking out.
• To use a credit on redbox.com or the mobile app: on the checkout screen, check the box that says “use credits.” Then log in to the account associated with your credits, confirm your credits and finish checking out.

So, they have come "clean", admit they've negotiated using audio "downgrade" of DD 5.1 as cost cutting measure.
Now I've got the facts from them, so how does that make you feel?
I'd like to see a sign on all the Redbox machines:
"Warning: Blu-ray disc may not contain lossless audio (Dolby TrueHD, DTS-HD Master Audio, etc), may contain lossy audio format such as Dolby Digital 5.1 / DTS 5.1, you rent Blu-ray as is, no refunds given".
I posted this on Redbox comments to the movie, curious how long it lasts there before they delete the comment.
