* What best DVD-R or DVD+R?
The DVD-R format was developed by Pioneer in 1997 vc DVD+R in 2002 by Sony.
DVD+R format was not an official DVD format until January 25, 2008.
DVD-R(W) and DVD+R(W) format are incompatible.
DVD-R(W) use amplitude modulation, DVD+R(W) use phase modulation, so more reliable.
On multi-session DVD-R(W) disk any session take up to 96 MB in time on DVD+R(W)
every session take exactly 2 MB.
DVD+R(W) win!
