Not all writers can write with the same quality to a given media, regardless of its quality. While lower quality media rots even if it's stored correctly, I found out that lower quality writes to higher quality media generates more read errors down the road, due to different readers' characteristics.

i.e. You can always read the disc you have burned with the original burner, but it's not guaranteed to be read by a future drive without errors or serious retrying in some sectors. Only three writers I had (HP 9100i, Yamaha CRF-F1, and a Samsung DVD writer with Lightscribe support) made high quality burns which can be read at full speed by anything which came before and after them, regardless of the media age.
