The DVD sizes can be a bit confusing. There are basicly 4 different DVD Sizes, DVD-5, holds around 4 700 000 000 bytes and that is 4.37 computer GB where 1 kbyte is 1024 bytes* . DVD+R/DVD+RW and DVD-R/DVD-RW supports this format. Also called Single Sided Single Layered. This is the most common DVD Media, often called 4.7 GB Media. DVD-10, holds around 9 400 000 000 bytes and that is 8.75 computer GB. DVD+R/DVD+RW and DVD-R/DVD-RW supports this format. Also called Double Sided Single Layered. DVD-9, holds around 8 540 000 000 bytes and that is 7.95 computer GB. DVD+R supports this format. Also called Single Sided Dual Layered. This media is called DVD-R9, DVD-R DL, DVD+R9, DVD+R DL or 8.5 GB Media. DVD-18, holds around 17 080 000 000 bytes and that is 15.9 computer GB. DVD+R supports this format. Also called Double Sided Dual Layered. * In the computer world is 1 KB data = 1024 bytes so 4 700 000 000 bytes / 1024 = 4 589 843KB / 1024 = 4482MB / 1024 = 4.37GB. See section 3.3 in the DVDDemystified FAQ here. DVD+R/DVD+RW/DVD+R DL and DVD-R/DVD-RW exact sizes DVD-R/DVD-RW = 4 706 074 624 bytes ( 4488 MB ) DVD+R/DVD+RW = 4 700 372 992 bytes ( 4482 MB ) DVD+R DL = 8 547 993 600 bytes ( 8152 MB ) DVD Write and read speeds Single Layer(4.7GB) write speeds 1x (CLV) = about 58 minutes 2x (CLV) = about 29 minutes 2.4x (CLV) = about 24 minutes 4x (CLV) = about 14.5 minutes 6x (CLV/ZCLV) = about 10-12 minutes 8x (PCAV/ZCLV) = about 8-10 minutes 12x (PCAV/ZCLV) = about 6.5-7.5 minutes 16x (CAV/ZCLV) = about 6-7 minutes Dual/Double Layer(8.5GB) write speeds 1x CLV = about 105 minutes 2.4x CLV = about 44 minutes 4x CLV = about 27 minutes Single Layer (4.7GB) read speeds 1x read speed is 1.321MB/s = ~56 minutes 6x CAV (avg. ~4x) read speed is max 7.93MB/s = ~14 minutes 8x CAV (avg. ~6x) read speed is max 10.57MB/s = ~10 minutes 12x CAV (avg. ~8x) read speed is max 15.85MB/s = ~7 minutes 16x CAV (avg. ~12x) read speed is max 21.13MB/s = ~5 minutes * write speed time and read speed time is not the same because writing requires some extra steps and also does the faster writing above 6x usually use lower write speeds for some parts of the dvd. 4x DVD speed = 36x CD speed. See section 4.2 in the DVDDemystified FAQ here. Other non-standard special DVD formats: DVD-VCD is basicly a VCD authored on a DVD. DVD supports the VCD resolution but the audio has to be resampled to 48 khz. If the audio is resampled to 48 khz it is standard DVD-Video. Read more here how to make a such.
