Are you manually creating a BR title and disc?
Way back when folk would try to build a VideoDVD by making folders and stuffing files into "the right folders" and then complain it didn't work. Even I tried that and after a few lost sessions moved to video media creation tools. Examples would be Sony Vegas or Final Cut Pro HD.
Good luck in getting Samsung to answer since I've yet to find any maker to help sort out user created media.
Nod to using tools that create the discs.
My 3D Blu-ray Samsung E-5900 refuses to read a licensed 3D Blu-ray disc (says "unknown file format"), although the disc is written in standard format (BDMV folder with STREAM and SSIF subfolders, .m2ts and .ssif files; UDF 2.50 file system). What can be the cause? The User Manual states that 3D Blu-ray disc type is compatible; can it be misleading?
