When burning CDs/DVDs (any software), there's always a chance that some bits gets burned incorrectly. The probability increases with the burning speed and the quality of your hardware. For most discs, containing music, videos, images and whatever files you burn, it doesn't matter if a few bits are wrong, no one would notice the difference in a video. However, for highly compressed data, common on linux ISOs etc, it can cause weird errors.
Basically, to avoid it, set the burning speed as low as possible! To actually check integrity, you need a hash of the correct image and then do a hash on the burned disc and see if they match.

right Lundis, just 1 little correction: I wouldn't set the burn speed as low as possible, especially high quality blank disks are optimized for high speed, so when it says "16x" the best is to use the next slower one (8x in this case).
if using cheap no-name ones you can go 2 steps lower (4x in this case).
and yeah, sometimes the burning process simply fails, but if it happens too often (and with different blank disk brands) it points to a problem with the drive....either the writing process is unreliable then or the reading process (when the data is burned properly but reading works unreliable it will also show integrity errors).
