  Why don't some RealNetworks Audio/Video play on my computer? RealAudio and RealVideo streams on www.nortel.com are encoded to play over a simple dial-up connection with enhanced play over a T1 or LAN. The faster your connection, the better the quality will be. While most Real media on this site will work with older versions of RealPlayer, these high-end streams require RealPlayer G2 or greater. We recommend downloading the newest version of RealPlayer. Be sure to check out RealNetworks' Technical Support FAQ's for more information.
