How do I play back the DVDs that I have copied to my hard drive

I can copy the dvd files to my hard drive but my media player or itunes wont play them any ideas… i realize this is probably an easy fix but I’m a little dumb when it comes to computers

I don’t have itunes but WMP should work if you open the .ifo file
Use the “File” Pulldown /Open In the windows lower right corner Pulldown select “Any File” & Open.

Either .ifo should work . One will be the menu.

If that doesn’t work you can do the same as mentioned above but install VLC Player as you may need a codec to play movies. Vista/Win 7 WMP should though.
