Sorry if this is the wrong place to post, but haven't found any info anywhere that can tell me my dvd burners "possible" life expectancy! I have a new Dell 8400 with a Philips dvd 16x burner. I burn a lot of dvds at about 4GB each. My question is how many can I burn before something goes up or wears out? What usually goes up in it first and how can I tell when I'm having problems with the burner and it's time to get a new one? I'm new to this so any info would be helpful! Thanks!
