Multicast issues - (security-failed) Early security checks failed

folks

i setting up an asa (5540) to allow multicast traffic from an upstream server, on a DMZ interface, through to the inside interface so i'm doing a bit of preparatory investigation

the streaming server is 10.12.65.12 and i have an mroute statement

mroute 10.12.65.0 255.255.0 DMZ

the DMZ interface has a security-level 0

i have multicast routing enabled and igmp enabled on the DMZ and Inside interfaces and i can see a PIM neighbour on the outside

one of the multicast addresses is 239.192.65.10

my problem

when i run

packet-tracer in dmz udp 10.63.65.12 58657 239.192.61.10 1234

i get the following

Result:      
input-interface: DMZ
input-status: up
input-line-status: up
Action: drop 
Drop-reason: (security-failed) Early security checks failed

i've only seen a couple of posts about this but there are no resolutions so i'm particularly keen to get this sorted before i have to deliver the streaming media

has anyone any ideas or views?

thanks to anyone taking the time to read this or to reply

greatly appreciated

apologies there's an error in the mroute statement

mroute 10.12.65.0 255.255.255.0 DMZ

Hello ,

The packet tracer drop is expected:
