I'm using Nero Recode 188.8.131.52. I'm trying to encode a movie that has a Dolby 5.1 soundtrack to Nero Digital 5.1 audio. On the main screen, when I choose Dolby Digital 5.1 from the original movie, I only get for "Encode Nero Digital Audio" the "Stereo" option. The "5.1 channel surround" option is grayed out. When I click on Settings, under Audio Channels the only choice available is Stereo. I tried all the Nero Digital categories and profiles, but nothing works. I did a clean install of Nero, nothing changed. Any ideas?
