The list of file formats that the program is capable of running includes the following: AVI, 3GP, ASF, FLV, Matroska, MOV QuickTime, MP4, NUT, OGG, OGM, RM, DIV, and many more.
Rules Player also stands out because it includes an onscreen information system (OSD) that will provide you with some details about the file you are currently playing.
And, subtitles here use softened shadows with antialiasing, making it easier to read them. Rules Player supports 12 different subtitle formats (MicroDVD, SubRip, OGM, SubViewer, Sami, Vplayer, etc.).
