replacing the malfunctioning drive as they're really really inexpensive.
You can check over at Newegg.com, see which ones the buyer's rate best and pick one.
It's a Sony Vaio with a Pioneer DVD-116 player. It doesn't work. I tried uninstalling it. Driver changes. If I click on the DVD in My Computer I get the message to insert...in disk drive even though there's one in there. Also, if I insert a DVD into the drive the drive light doesn't light up as it does in the CD drive. The only thing that happens after I insert the DVD is I'll see the flashing tiny DVD symbol for a short time, then nothing.
