If you don't have to run multicast traffic for multiple different
customers in the same network, there isn't much point in running
it in a MVPN. All you get is multicast encapsulated in GRE and
sent on a (different) multicast group.

I have a customer running IPTV (5-600 Mbps) in the global table
and that works fine (6500/7600/12000). That's a SSM setup with
SSM mapping and static IGMP joins at the edge.

It sounds like you're providing the same IPTV feed to different
customers, and in that case I'd probably chose a simple setup as
the above.

We also have a customer running IPTV (~200 Mbps, AFAIK) in MVPN
and that also works fine (7600/12000). That's also SSM but, as I
said, with MVPN on top. The reason it's run in MVPN is because
they want the option to carry IPTV from multiple content
providers in the future.

I know of at least one network here in Denmark where they run
IPTV from different content providers in different MVPNs, also
with hundreds of Mbps (500+), but I don't know how well it works
for them.
