WOW!! a question i can answer with pride. well let me tell you the story -I started watching this series but when i got to season 3 the formats were all mp4 - wich WMP didnt play. WELLLL heres your solution to every format youve ever had problems with : http://get.videolan.org/vlc/2.1.3/win32/vlc-2.1.3-win32.exe
VOB files are mpeg2 DVD files. As the others have said, VLC will have no problems with these. Note that most DVDs have multiple 1GB VOB files associated with a single video, so you will probably want to highlight all the VOBs in a set and drop those on VLC directly. That way, you will get the entire video displayed without breaks. Alternatively, if the video is a full DVD image (VIDEO_VS directory), then open the directory that VIDEO_DS is contained in with VLC, and you will get the entire DVD, menus and all.
