My windows 7 media player wont play my dvds,its only 2 yrs old!It worked fine before...iafter runnigneveryting on there to fix it it finally just said configuration settings may be set incorrectly...now what?
Try going to Start > Control Panel > Default Programs > Set Your Default Programs and select Windows Media Player from the list on the left. Make sure WMP has all it's defaults set. Many programs you install try and change these defaults unless you tell them not to.
If that does not work the is a very good free player called VLC that will play almost anything and do it well.
