Free things that I recommend and are useful and safe.
VLC media player
VLC is a free and open source cross-platform multimedia player and framework that plays most multimedia files as well as DVDs, Audio CDs, VCDs, and various streaming protocols.
You can find it here VLC Homepage. It's about the only player I use. I rate it a 10 out of 10.
