Detailed explanation-1: -It uses digital compression. Poorly compressed audio or video may be blocky, fuzzy, harsh, or vague. The audio downmix process for stereo/Dolby Surround can reduce dynamic range.
Detailed explanation-2: -DVD-RAM is much faster and easier than CD/DVD-RW at overwriting data. DVD-RAM discs can be rewritten over many many times (over 100, 000). Data can be reliably stored on DVD-RAM for many years due to their high quality. DVD-RAM has a capacity of 4.7GB (or 9.4GB with with double sided discs).
Detailed explanation-3: -DVD-R and DVD+R are nearly identical formats. The discs look the same and are both supported by most DVD-ROM drives and DVD burners. The only difference between the formats is the way they determine the location of the laser beam on the disc.
Detailed explanation-4: -From a technical perspective, the DVD-RW format requires shorter time to burn the lead in/out, and therefore has slightly more compatibility with DVD players. On the other hand, the DVD+RW format has some special features, such as lossless linking, and both CAV and CLV writing.
