Hi were you able to get resolution? on this forum post?
http://forum.snomone.com/index.php?/topic/4627-rtp-stream-input-multiple-live-moh/page__p__20137__hl__music__fromsearch__1#entry20137
also how can we reproduce this? are you using VLC if so what is the syntax you are using? so we can start testing this here.
