Please note it?s come to our attention that the first run of DVDs (not Blu-ray) have a default audio setting of DTS Surround Sound. So, if you?re putting your DVD in your player and the audio is silent, it WILL work but you?ll just need to change your audio set-up. When you put the DVD in your player please go to “Set Up” on the DVD menu and select “Dolby 2.0″. And, Voila! Loud noises will begin! All remaining product going forward will have a sticker on it explaining this process. All new product manufactured will have this default fixed. We apologize for any confusion!
