What is XviD
XviD is the name of a popular new video codec being developed as an open source project by volunteer programmers from all over the world. The format was created to offer a free alternative to other commercial video codecs, and despite being open source its quality and efficiency has made it one of the most popular video codecs online. While XviD still isn't as widely used as DivX, playback of XviD movies is usually supported in new DVD players nowadays.
The XviD codec makes it possible to compress a full-length DVD-quality movie enough to fit on a single CD (might require 2 CDs depending on the length of the movie), while still maintaining the original image quality. Despite the fact that XviD movies offer higher quality video at smaller file sizes they take less time to encode than MPEG-2 due to the incredible compression technology. The video is usually combined with MP3 or AC3 audio to enable both high quality video and audio. These factors and the fact that the codec is distributed for free has contributed to the success of the format.
When you install the XviD codec it basically provides your system with specific instructions how to compress and decompress video in the XviD format. Once you've installed the XviD codec on your system you will be able to play XviD videos using Windows Media Player or any other XviD-enabled player.

What is DVD
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.

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 )

kbps = thousand bits per second
Mbps = million bits per second
*2 approximately resolution, it can be higher or lower
~ approximately bitrate, it can be higher or lower
a DVD with lower video quality, similiar to VCD/SVCD video quality
* the video quality depends on the bitrate and the video resolution, higher bitrate and higher resolution generally means better video quality but bigger file size
