In xbmc i use "advancedsettings.xml" <discstubextensions> <add>.bluray|.dvd</add> </discstubextensions> And i create some file with the nane of my blu-ray or dvd, xbmc nows if it's a blu-ray or a dvd, and put the logo. (use list.txt and *.bat to do a directory and a file with the same name)
On XMM : Options -> Device scanner -> File Extentions add "bluray" and "dvd"
