The page in question was updated with following two paragraphs: What does plus stand for in DVD+RW/+R? The key feature of DVD+RW/+R media is high [spatial] frequency wobbled [pre-]groove with addressing information modulated into it. This makes it possible to resume interrupted [or delibirately suspended] burning process with accuracy high enough for DVD[-ROM] player not to "notice" anything at playback time. Recovery from buffer underrun condition in DVD-RW/-R case in turn is way less accurate procedure, and the problem is that the provided accuracy is very much what average player can tolerate. Now given that both provided and tolerated inaccuracies are proportional to respectively writing and reading velocities there basically no guarantee that DVD-RW/-R recording that suffered from buffer underrun will be universally playable. Sometimes DVD+RW/+R is erroneously compared with packet writing. Packet writing means that every chunk of actual user data gets surrounded by so called link, run-in and run-out sectors, which wastes some capacity, not to mention that it requires explicit support by player's DSP [Digital Signal Processor] performing the actual decoding of user data. Again thanks to high frequency wobble, no such things are needed for DVD+RW/+R. This is exactly why it's commonly referred to as "designed from scratch for maximum compatibility with DVD-ROM specification."
