I've had a disc in my MK IV nav computer since I got the car (September 2002 - the first month that DVD computers were used) and I haven't had any problems with the drive wearing out. I used to run backup copies of my map discs (and keep the original in the glove box) because I was worried what might happen to the disc when the car hit a pothole. But given how twitchy that drive is with burned discs - and never having a disc damaged - I went back to using the original in the drive.
