There might not be such a tiny video player, so austere, basic and simple as MiDivX in all internet. This utility has the advantages and disadvantages of every small application: it offers just a few functions, but it performs them at ease.
Being such a small player, it is ideal to run it on PCs that don't have high hardware resources. It is also very useful when you don't want to waste PCs resources assigned to another activity.
MiDivX does not include the necessary codecs to play films, but it accepts any package that is installed on the PC.
MiDivX is also an excellent option for those people who are just getting into the world of PCs and want a simple application to learn little by little the functions of each program.
