This problem is one of the simplest problem to solve... In windows
anyname.dvdmedia will open as any other folder, inside should be
VIDEO_TS folder, open it, then there will be many files with file
extensions *.IFO, *.BUP, *.VOB; you can open any of these files with
Windows Media Player, it will open the entire movie, don't worry about
it. For the first time you have to double click the file, then Windows
will prompt you to open the file with a program or search in internet to
a proper program, just click on Open With... then select Windows Media
Player or whatever media player that can play DVD movies. Now, if you
open the .VOB file with Windows Media Player, all files like this in the
entire system will be opened with Windows Media Player the next time you
open them.
