Out of the box, the 7MC Movie Library will display the default file types that it can play. (Link to microsoft article about default file types) In addition to the files on the this list, the movie library will also display movies that are ripped from DVDs and stored in video_ts and audio_ts folders. In order to have other file types displayed (such as MKV and .iso) which are not natively supported by 7MC, you will need to enable this file type via a “hack” or workaround. For example, with .mkv files this type is enabled when a splitter such as Haali media splitter is installed. Head to the forums if you are having issues with a specific file type being displayed in Media Center. Below is a list of common formats and their native (out of the box) support within 7MC.
