Does anyone here know just what "Verifying Burned Data" does with Nero Burning Rom? It seems like the obvious would be that it compares the data on the DVD-R to the image on the HD- is that really what it does? And will a positive result mean the disc is truly free of errors? I've never used this feature before just now, and since it takes 2x as long I want to know if it's really worth it or not. I got a message saying the Verification was successful, but what does that really mean for the quality of my DVD-R?
