Hi. It's usually toward the middle of the NeroHistory log section for a particular burn. You can also download DVD Identifier: http://www.dvdidentifier.cdfreaks.com ImgBurn and DVD Decrypter will also ID the media in Write mode in the righthand window pane. http://www.imgburn.com http://www.filehippo.com/download_dvd_decrypter/ Since you already have Nero, you can use the Nero CD-DVD Speed Tool or the Nero Info Tool as well. Taiyo Yuden media will show as YUDEN or TY or TAIYOYUDEN.
