When we are talking about movies that should not be viewed using the divx codec, we are thinking of the most basic divx codec which involves a relatively 
low quality of the picture and sound. We are talking about the format in which movies come at sizes of 700 MB or 1.4 GB at most. We have all had the “pleasure” of seeing certain movies in this format and in some cases, this is just not enough to enable you to fully enjoy in the movie in question.
The first on the list of these movies is Blade Runner. This is one of those movies that rely on atmosphere to get you involved. Seeing Ridley Scott’s dystopian LA in such a bad format is like listening to Mozart underwater. You do not get half of it, at least. This is especially true for the latest restoration which is available on Blu-Ray and which is simply stunning. There are so many scenes that lose all of their impact when you watch Blade Runner in the basic divx format. For instance, one of the very first scenes in which Harrison Ford is flying over LA of 2019 loses almost all of its epic grandeur if not viewed in a quality that can do it justice, and the basic divx format simply cannot. Luckily, with the divx codec pack, you also get support for bigger formats that will give you a much clearer picture of what LA is going to look like in just a few years.
Another one of the movies that loses plenty of its impact when viewed in sub-par formats is Lawrence of Arabia. It is an old movie, from the 60s to be more precise and it is generally known as the best epic movie of all times. There are even people who claim that the only way to see this movie is on the big screen. However, as most of us are not really in vicinity of a cinema that would play Lawrence of Arabia, we depend on digital copies of the movie to try and bring the Saharan desert to us, with all the plot meanderings and larger-than-life stories and dilemmas. And if you try and watch this movie in the basic divx format, you are definitely missing out on one of the most amazing epic stories of all times. There may be innumerable grains of sand in the Sahara, but there is no need for grainy or low quality picture or sound.
Ben Hur is another older movie that simply needs to be seen in formats higher in quality than the basic divx format. It is another epic with grand scenes that will be compromised unless viewed at least in the H.264 format, which is luckily supported by divx codec pack. For instance, the chariot race, one of the most memorable movie scenes of all times is not supposed to be seen in low quality
and you will actually miss the point of it all. Only when you can see every last detail can you appreciate the skill and the courage that went into making that scene.
These are just some of the examples that we could think of and the list of movies that require a finer format in order to be fully appreciated is a huge one. Let us just name a few movies that will be definitely ruined by the use of the basic divx format: Alien, any movie by Tarkovsky, Once Upon a Time in the West, Saving Private Ryan, Sympathy for Lady Vengeance, Duelists, Apocalypse Now, Godfather and Godfather II, Pan’s Labyrinth and a whole bunch of other movies, mostly newer releases. Older movies we are used to seeing on our TVs which up until recently offered exclusively not that great quality.
