DVD stands for Digital Versatile/Video Disc, DVDR stands for DVD Recordable and DVDRW for DVD ReWriteable. If you’re familiar with regular audio/music CDs or regular DVD-Video discs, then you will know what a recordable DVD looks like. A recordable DVD stores up to 2 hours of very good quality DVD-Video, including several audio tracks in formats like stereo, Dolby Digital or DTS and also advanced menu systems, subtitles and still pictures that can be played by many standalone DVD Players and most computer DVD-ROMs. If you choose to lower the video quality it is possible to store several hours video on a recordable DVD using low bitrates and low resolution with video quality more like VHS, SVHS, SVCD , CVD or VCD . It is also possible to have up to 4.37 * GB ordinary data or mix DVD-Video and data on a recordable DVD that can be played by most computer DVD-ROMs.

 

 

There are three competing DVD Recording standards, DVD-R/DVD-RW and DVD+R/DVD+RW have pretty similiar features and are compatible with many standalone DVD Players and most DVD-ROMs while DVD-RAM has less DVD Player and DVD-ROM compatibility but better recording features.

DVD Sizes

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.

 

DVD-SVCD

is basicly a SVCD authored on a DVD. DVD do not supports the SVCD resolution but it may anyway work and the audio has to be resampled to 48 khz like the DVD-VCD. Read more here how to make a such and download a DVD Sample including a DVD-SVCD here .

 

DVD-MP3

is MP3s burned on a DVD but very few MP3 capable standalone DVD Players supports it because most Players verify DVD as DVD-Video only. Check our DVD Players list for compatibility.
