I have a 4-yr-old Sony Vaio laptop with a Blu-Ray player/CD burner combo. It stopped playing a few months ago and my laptop is out of warranty. Besides, the dealer where I purchased it is 90-minute drive one way (I'll never do that again!) I'm running Windows Vista. The device is Matshita BD-MLT UJ-220S ATA. Through Device Manager I searched for updated driver software to see if that was the problem, and the result was "the best driver software for your device is already installed." But when I insert a DVD, it spins for 4 seconds then stops. It's not showing the drive at all in my My Computer list. What's going on?
