You understand correctly. The source,PE's and the receiver are on the
same MX running Junos 12.3R3.4.
Removing PIM from lt-1/1/10.770 is not a solution because the PE will
not learn about the source and the multicast group.Changing the
multicast group didn't change anything.

Do understand correctly that the source of the traffic is a logical-system on
the same router? How are you generating the multicast traffic?
I believe the issue is running PIM on the first-hop interface facing the
source. The router is expecting either PIM-register encapsulated traffic from
upstream, or expecting to already have PIM join state.
Can you try removing PIM from lt-1/1/10.770 in routing-instance x and
configuring lt-1/1/10.770 to forward multicast traffic without running PIM (set
routing-instance x routing-options multicast interface lt-1/1/10.770)?
If that doesn't help, please provide config of the logical-system containing the source, and the outputs of
"show pim rps extensive [instance instance-name]", "show pim join extensive [instance
instance-name]", and "show multicast route extensive [instance instance-name]".
If you're still having issue, you may also want to try a different group
address to avoid any peculiarities with adminstratively-scoped addresses.

Hello,
lo0.777 has the rp address, and the lt-1/1/10.770 is the link between PE and
multicast source (it's a single MX with logical-systems and I already tried the
same setup with physical interfaces between PE and CE with the same result):

Hi Mihai,
Doesn't ring a bell at first sight. What's the configuration of interfaces
lo0.777 and lt-1/1/10.770 ?
Thanks,

Hello,
I have a basic setup with 2 PE's (X and Z) , one multicast source
attached
to X and one receiver attached to Z.
I configured a NG-MVPN with rsvp-te between PE's but X doesn't send SA
autodiscovery to Z so the traffic is dropped.
