When you already have the better format, people would be wondering why there is a need for some to convert DVD to MPEG quality. For one, you already own the higher quality format so why would you want to transform it to a lower one? Well one of the answers here is playback. Not all players may be able to read DVD format files and rather than letting them go to waste, it would be better to transform DVD to MPEG since the latter is known and familiar for most readers and playback contraptions.
While there may be some diminished quality of sorts stemming from it, the fact remains that seeing the movie is still the essential part of converting DVD to MPEG. MPEG can be viewed from computers and standard VCD players. It can be still read by some DVD players, but knowing that some have been notorious in selecting the type of DVD files to show, MPEG offers an easier and accessible way of playing films and movies.
Sound and video quality may be brought down a notch. But the thing is, if there are level to which MPEG could be classified, a downgrade to MPEG offers much better quality over standard MPEG files. Compression factors are one thing to be considered. Whenever you convert DVD to MPEG, you are sacrificing bit rates and pixels just to get the job done. You will not notice this when you play back the MPEG file. But one thing you may not notice is that the quality is better than your other files that use MPEG as their main format.
Depending on how you look at it and the intentions, MPEG is a universal and easier format to handle. Converting DVD to MPEG may take some time as well. However, rest assured once you have completed the task, you will enjoy movies and watch them as often as you like without any more worries of not being able to be played.
