 * Within the elps lab each computer is equiped with a DVD RW drive. The most popular or utilized source to display video other than a you-tube and storing a video on a flash drive, is to have the video burned on a DVD-Disc for playback in the classroom. **


 * The eLPs staff requires that faculty bring their own blank media for recording purposes. Among the DVD Formats DVD+R, DVD+RW and DVD-R. Here are the differences: **


 * DVD-R has a storage capacity of 4.7 GB and it is considered better to use DVD-R discs to record on if the supported formats for the DVD player that the disc will be played on are unknown. DVD-R was established first so the systems that may be older are more prone to not work with DVD+R. DVD-R also do not have to be formatted prior to burning such as DVD+R. However, DVD+R are less susceptable to error and interference in its tracking and speed control. DVD-R is also a write only once disc so once you write a movie to it that is it. DVD-R have 3,000 more data sectors than DVD+R and 7,000,000 more gigabytes of space. So DVD-R is a little larger. DVD-R was the first DVD used for movie playback **


 * DVD+R has a 4.7 GB storage capacity and is considered to be better for storage of audio, video and other data as opposed to movie playback such as DVD-R. While DVD+R will playback movies just fine. DVD-R gains more favorability in the fact that they are slightly larger. As far as price compatibility, they are usually priced the same. DVD+R will work well for most small movies or clips, but if a large project requiring a lot of space is being conducted DVD-R may work better. Of course the DVD+R must be formatted prior to being used and like the DVD-R it is a use only once type of media. DVD+R are also newer in production so a benefit is that they are more likely to play on newer and older DVD players as opposed to DVD-R. **


 * DVD+RW also has 4.7 GB of storage capacity, unlike the other formats DVD-R and DVD+R, you can rerecord over DVD+RW up to 1,000 tines according to the manufacturer. DVD+RW are also used for storage media that will need to be updated when changed, such as backups to databases or a collection of files that may change and need to be rerecorded. DVD-RW is the same as DVD+RW only that it has more storage vectors and bytes than DVD+RW, just as with the one-time recording discs. **


 * DVD+R DL discs have more storage capacity than that of their single layer counterparts. DVD+RL discs have 8.5 GB of storage space, but in the case of Double Layer discs, DVD+R DL has more storage sectors and more bytes than DVD-R DL. **
