It looks to me like a bug with the mrouted code. As for the non-propogation issue, it was due to using a crap network card (dc0) that was having multicast issues. Swapping it out with a 3com solved that problem. -Crh Charles Henrich Eon Entertainment henrich@msu.edu http://www.sigbus.com:81/~henrich To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-multimedia" in the body of the message
