Dvd burner stops working as a drive and burner.

[splagl]

I recently was asked by my mom to burn her a disk onto a dvd. So on her computer after I take the dvd out it still shows as it being in and when I try to write on the disk it says windows is using the disk please wait. So I do and still nothing. But my main problem is when I tried it on my computer nothing is showing up in the drive. The blank disk doesnt appear no movies I put in nothing. It used to work. What do I do?
Thanks

First, try emptying the CD Burning cache in:
C:\Documents and Settings\username\Local Settings\Application Data\Microsoft\CD Burning (you may to unhide folders in Folder options first).

Next check Device Manager and make sure the drives are showing under DVD/CD-ROM Drives.

Next, try the upper/lower filter fix in registry. You can download fix from :
