Hey All I downloaded a demo disk to test the audio of my home theatre. The disk was a blu-ray compilation. After unzipping everything to my HD, there were 3 folders: - BDMV - CERTIFICATE - SLY! Using the guidelines from the link http://www.afterdawn.com/guides/archive/burn_dvd_folder_imgburn.cfm I burned a double-layer DVD with the contents. The problem is: my PS3 does not detect it as a blu-ray, but as a data disk. I shows the folders and I was able to play the videos inside the folder stream. Now the biggest problem: absolutely no audio. Any clues of what went wrong? Many thanks in advance! MrHawk
