After installing alcohol, nero info tool can’t read correctly the media manufacturer 
.
Hope they (alcohol or ahead) fix this at a latter version.
Thx for information.
Not a bug, this is a feature.
Go to Alcohol emulation options and uncheck the “ignore media” option. This option is required to run many games from CDR/RW, and is the reason that you must have Alcohol installed in order to run copied games in many cases.
