RTP Player is a Real-Time Transport Protocol client which is able to play Networked Multicast Live Streams. You can import URL's from M3U Files and enter them manually into your personal RTP Player Database. The M3U File Import automatically prevents the import of URL's which are already in your Database. If you enter an URL manually which is already in your Database, RTP Player will inform you. This makes maintaining your personal RTP Player Database very easy.
