I have finally decided to upgrade from 22.214.171.124 to the latest version. I am disappointed Nero did away with the numerous choices the older version of the Nero Digital audio plugin had, for this new version of no choice except bitrate. But I did save my .dll's from 126.96.36.199 so at least I can still use them in the latest version of Ultra. Does anyone know of or have a more updated version of the old Aac.dll (my date is 11/17/2005) and aacenc32.dll (my date is 2/23/2006)? Or was 188.8.131.52 the last version of Nero with them included? Thanks!
