I've been auditioning media players over the past few days to find one that really stands above the others. It really came down to MixZing and Rock' On, both very good players. I've settled on MixZing as my primary player (for now) for it's highly intuitive interface, solid audio/video playback features, and social networking integration. Make no mistake, Rock' On is a very good player, and far more visually striking, but for functionality, MixZing wins this round (for me at least). Are their any others I should try?
