ratDVD is a program that compresses DVD movies maintaining the quality and the original structure.

There is a multitude of programs to preserve the information of a DVD movie. We can convert DVD movies to another format, such as DivX, XviD, mkv, etc. Or we can select specific parts of the film (menus, extra scenes, etc.) to create a customized DVD.

ratDVD allows us to movie DVDs, make copies, and save them in their format. The advantage of using this program is that we can keep the original DVD entirely and simultaneously reduce the movie's size. When converting a DVD to ratDVD format, it stores all DVD information in a single file with the .ratDVD extension. This way, we can easily make backups from all of our DVD movies.

To reproduce the ratDVD format, we can use many existing video players, such as Windows Media Player or KMPlayer. Some media players, such as ZoomPlayer, need to install an additional file to play .ratDVD format. If we want to convert .ratDVD format to DVD, we can do it with this program, so we can “recover” the original DVD format and play it in any media player.

The program's main function is to preserve DVD movies with all its features: menus, scene extras, subtitles, audio tracks, etc. Even so, there is the possibility of selecting those items that we want to preserve. If we choose only the main movie and apply image compression, we can reduce the size of a DVD-9 to 1.xx gigabytes, which implies significant space savings.

The program's goal is to have our DVD movies collection in digital format; that's why we have the option of downloading movie posters, along with other information such as: the director, actors, release date, etc. This information is stored in the .ratDVD file generated, so we can consult all the information downloaded at any time. In addition, in Windows Explorer, the files with .ratDVD format will show the movie poster (in the case it has been downloaded). This way, we can quickly see our collection of movies and select the one we want to watch.

The program does not support any copy system, so if a DVD movie disc is copy-protected, we will not be able to use this program to make a backup copy.

This software is free, and despite not being updated since 2005, it can be used ideally as it retains all of its functionality and can be helpful for many users.
