Kodi and VLC Player are two of the best free all-in-one media players. Kodi is a genuine all-in-one media player and supports all major music and video formats, supports DVDs and Blu-ray, and Internet streaming of music and video from Netflix.
Originally designed as the media center for X-Box, it handles physical discs as well. It is customizable, features visualizations and a variety of add-ons, but users report that it tends to be memory intensive.
VLC Player lacks Blu-ray support but it plays nearly every video format and handles audio surprisingly well. It is open-source, light on resources and does not pack adware. Video displays with excellent clarity as installed, but the program features numerous settings for further customization. Despite the lack of Blu-ray support, it is worthy of consideration.
