I have a windows based computer which has windows 7 operating system. I recently upgraded from xp. I used a program to play DVDs on my computer but I think that software does not with windows 7. It worked fine with windows xp. So I think I need a dvd player software to play my DVDs with windows 7. So guys please suggest a few good softwares for the same. One more thing since this is a new windows version, is there any program within the windows 7 which I can use to play DVDs. Please also tell how to use it.
