Media Players and Encoding
Recommended by Cath Le Couteur:
VideoLAN and the VLC Media Player
As a media player it plays absolutely everything, it’s cross platform, it’s open source/free and now with the latest version you can export your files into a myriad of other formats, including the very good .mp4. For people with HUGE file sizes who need to reduce the size but keep quality, I’d definitely vote VLC as one of the best options around. Simply go to File/Wizard in VLC.
