Nero Recode - allows you to compress a DVD-Video volume of more than 4.7 GB in files of 4.7 GB. The program compresses the video data so that it fits easily on a single-layer DVD-ROM, with virtually no loss of quality. In the process of copying, you can also delete unwanted material, which is normally present on the original DVD (subtitles, additional audio tracks). Thus, by removing unnecessary, you can make room for the original video quality improvement. With Nero Recode, DVD-ROM can be saved on the hard disk of a personal computer in the form of video files-DVD or in the form of a disk image.
