The player is constantly buffering, why? I am on a 56k modem.

Symtom: When I try to listen to a programme, it is constanly being interupted by the 'buffering' message.

Reason: BIRSt now uses multiple bitrates, which means the appropriate stream is sent to the user depending on connection speed. Older versions of media player do not support multiple bitrates and have to download the entire file, including the broadband portion, which requires a higher speed connection than 56k.

Cure: Download and install The Latest Windows Media Player
