Based on the open source Helix player, RealPlayer 10 for Linux has been released. Now you can experience the latest RealPlayer technology on your Linux desktop.
"RealPlayer 10 supports RealAudio, RealVideo 10, MP3, Ogg Vorbis and Theora, H263, AAC and more. Get ready for accelerated video, full screen playback, and a lot more."
I noticed with interest that the new player is GTK aware, which means that it will detect your GTK theme and skin itself accordingly.
