Hi,
First of all, you could have simply installed a new program then changed what program was utilized when you inserted a DVD.
Windows does not natively come with the codecs to decode DVD video.
*Try installing THIS (the "Standard" version):

Then assign the program that comes with it to autoplay DVD's when inserted (WMPC-HC).
other:
- it installs codecs that can make other programs, including Windows Media Player function.
- you can manually start a DVD from the video folder. File name is "VIDEO_TS.ifo"
- where did you get the Lenovo software from? Can you download it from the laptop site?
- changing defaults (can be tricky)

- some people use VLC, but I prefer KLite Standard. I play ALL of my video from it.
- *For any file type you can right-click and say "OPEN WITH" -> "choose another app" then choose the program you want to use whenever you open that file type (wording slightly varies by version of Windows)
