Hi All,
I have 2 VSPs 4450 connected via V-IST working good.
I am trying to connect a ERS in both VSPs with MLT.
ERS = Standard MLT (Ports 1 and 2)
VSPs = SMLT (Port 12 each switch)
When I leave MLT connection on the VSP as standard it works good but when I enable the SMLT I lost connection.
Any suggestions?

No I mean do not touch the configuration (leave smlt enabled on MLT 1 on VSPs) and just shutdown one leg. The value of MLT CURRENT should change from smlt to norm. Then try to reach the switch.
It would also be interesting to see "show vlan interface vids 1,2" and "show vlan interface info 1,2" on ERS. But I believe you've already doublechecked this.

No, if I enable the SMLT in one leg I lost comms.

I thought there might be a problem with SMLT-VIRTUAL-BMAC. But according to the output it is also set on both VSPs. So it is in state when you disable one leg of SMLT the ERS starts to respond?
