This is the first LightScribe burner that I've owned (I've used about a dozen other non LightScribe burners in the past). I've used this new Lite-On LightScribe unit for reading CDs and DVDs (both +R and -R) without any issues. I've also burned both CDs (-R) and DVDs (-R and +R) with it without any issues. My system is a top end DELL XPS 9000, Win7 64bit Pro, and I didn't have any issues getting the burner to work in it. I bought HP branded "LightScribe" DVD media, and I was looking forward to burning some nice labels onto the top of my DVDs. My first attempts didn't turn out too well, the image and writing that I'd selected was too light, too hard to see once it was completed. I don't think this is an issue with the burner, or with the media, but with me and my lack of practice with selecting a good image that will burn dark enough to be easily seen. I know now (trial and error has taught me) to make sure the labels that I make need to have strong contrasting text and/or pictures, so that when burned onto the tops, they will be easily seen.
I'm giving this burner a 4 out of 5, because I wanted the LightScribe option to be more user friendly (maybe it's a software issue, maybe the laser is not strong enough, or maybe it's just me, but better software and/or a better laser would have protected me from myself, and then I would have given it a 5.
