The issue could be that the application may have some issue with the same and due to the same it is not able to or the DVD drive is not functioning appropriately. So in order to make the things perfect or work out for you it would be beneficial that you check for the thing that is the application that is installed do not have issue. Scan the system.

There is another possibility that the system may be affected by virus and hence this is the reason that the application not able to perform. You need to scan the system using a good antivirus application that is Quick heal which may detect the threat and then make the drive to work with the application as well. So do check out for the thing.

Try uninstalling the application that you have and then check out whether the drive is able to work. It may be that the application has some bug that may be not allowing the dvd drive to work when been installed. In order to figure out that the issue is generally associated with the application uninstall the suite. Hope you may then get to a better conclusion for the same.

Well you need to perform some actions in order to make it work well. All you need to do is to delete the filters. For this you need to follow certain steps they are as follows:
  • Open the start button and type regedit in msconfig
  • Hit Enter.
  • Navigate through HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
  • Right click on {4D36E965-E325-11CE-BFC1-08002BE10318} entry, choose Export and choose export
  • Select Desktop in the Save in box and type backup in File Name. Click Save.
  • Highlight this key ({4D36E965-E325-11CE-BFC1-08002BE10318}), on the right pane, and then check if Upperfilters and Lowerfilters value are present. If so, please right click on the values and select Delete to remove them.
  • Restart the computer

You can also process the action that is uninstalling the DVD Rom and then installing it with the latest firmware. Get the latest firmware and then install it again by following the steps as mentioned below:

* Click on start menu
* Type devmgmt.msc and hit Enter
* Now right click on DVDRAM and then on uninstall
* Restart the system
* Upgrade the firmaware
