Is the recordable DVD solution that seems to be the most popular (out of DVD-RAM, DVD-R and DVD+R). it holds 4.7gb of data per side, and double sided discs are available, so discs can hold nearly 10gb in some circumstances. SVCD mpeg2 images must be converted before they can be burnt to DVD-R and played successfully. DVD>DVDR copies are possible, but sometimes extras/languages have to be removed to stick within the available 4.7gb.

The FHD or Full HD resolution of 1920x1080 pixels in a 16:9 aspect ratio was developed as an HDTV transmission and storage format. Using interlacing, the bandwidth requirements are very similar to those of 720p – their pixel counts are roughly in a 2:1 ratio, 9:4 exactly. FHD is 3 times the width and 2 1⁄4 times the height of 4:3 VGA.
Due to its origins, this resolution is sometimes referred to as 1080i wherein the i stands for "interlaced". Since there are also progressive signals with the same frame rate (but half the effective field rate) those signals are more commonly called 1080p.
BDRips are encoded directly from the BluRay disk, so should be of better quality than a DVDRip. They usually have a resolution of 720p (or 1080p), and are encoded using the matroska (.mkv) container and x264 codec.
BD/BRRips come in various versions: the m-720p (or mini 720p), which is a compressed version of a 720p and usually weighs around 2–3 GB; the 720p, which usually weighs around 4–7 GB and is the most downloaded form of BDRip; the m-1080p (or mini 1080p), which usually weighs a little bit more than 720p; and the 1080p, which can weigh from 8 GB to sizes as big as 40–60 GB. There are also mHD (or mini HD) versions available, which are encoded in lower resolution and are smaller in size.
This is a rip created by capturing video from a screen, either broadcast or using a service like Hulu or Netflix. Quality can range from mediocre (comparable with low quality XVID encodes) to excellent (comparable with high quality BR encodes). Essentially, the quality of the image obtained depends on internet connection speed and the specifications of the recording machine.
This is a movie or TV show downloaded via an on-line distribution website (web download) like Amazon or iTunes. The quality is quite good since they are not re-encoded. The video (H264) and audio (AC3/AAC) streams are usually extracted from the iTunes or Amazon file and then remuxed into a MKV container without sacrificing quality.
An advantage with these releases is that they mostly have no network logos on screen, just like BD/DVDRips.
VODRip stands for Video-On-Demand Rip. This can be done by recording or capturing a video/movie from an On-Demand service such as through a cable or satellite TV service. Most services will state that ripping or capturing films is a breach of their use policy, but it is becoming more and more popular as it requires little technology or setup. There are many online On-Demand services that would not require one to connect their TV and computer. It can be done by using software to identify the video source address and downloading it as a video file which is often the method that bears the best quality end result. However, some people have used screen cams which effectively record, like a video camera, what is on a certain part of the computer screen, but does so internally, making the quality not of HD quality, but nevertheless significantly better than a Cam or Telesync version filmed from a cinema, TV or computer screen.
