In the dvd to cd tutorial, a Nero plug in for ac3 is called for. I’ve been using Nero 6.6 for a year, but when I try to install the plug in nothing happens. It’s been extracted, and opens to the installation dialog box, but pressing the install button returns me to the plugin file.
I do not know what do you expect plug-in to do, but it usually allow the software it was meant for to do certain thing. In case of AC3 it will allow you to hear AC3 encoded sound. AC3 is common sound on DVD so if you play DVD on your computer and hear the sound, than plug-in works.
