This must be a bit dumb question, but bare with me.. This is newbie talking. I am about to rip/burn a disc, that has 2 movies (double feature). The whole disc is 6,3 GB, so it´s safe to say, that both movies are under 4,3 GB (so no compression needed when burning one movie from the disc). There are no extras or subtitles, nor 5.1/ DTS-tracks. I used MTR to rip the disc, and then went to the DVD2oneX. This "Compression Ratio" got me confused. It says (from the "help"): ____ "The Ratio popup-button allows you to select between 'Variable', 'Constant' and 'Selective'. **Variable Ratio: When selecting 'Variable' the 'old' engine is used for processing the movie. This will result in a movie quality know from recent versions of DVD2oneX v1.2.0. **Constant Ratio: Selecting 'Constant' will enable the 'new' engine for processing the movie. This will result in a much better movie quality than known from recent versions of DVD2oneX v1.2.0. This mode is especially for processing long movies. **Selective Ratio: Selecting 'Selective' will enable the 'new' selective ratio for processing the movie and will enable the level popup button at the right side. This new engine is a different way of approaching the video data! Selectable in three pre-defined levels, this new engine determines the balance in distincting the important screen parts from the less important ones. Things that are not in focus in the current frame, like backgrounds, are low in detail or as we define it, of low importance to the screen and can be approached differently than the important ones. With this new compression method, setting the popup button to low will lead into a scheme where the important parts of the screen are a bit more compressed than the less important ones. Compressing of low important parts can result into macroblock because the original encoder in a good encoder setup already achieved the best possible compression without loss of detail. In medium the important parts are even more compressed than the non important parts, and in high the compression is almost done only on the important parts." _______ So what shall I do, since I don´t want compression AT ALL? Am I using wrong software for this (when I don´t want any compression, but I still have to rip the disc, to get rid of the other movie). Thanks to you all. edit: Ok. I guess I have to use "Title Only Extraction" from MTR, since I can quite clearly see from the timecode which film is which..
