I have the same problem with my Seleco 120 on different remotes (have ordered my pronto, but has not arrived yet). Some remotes wont learn the Seleco codes at all and on the others (in my case a marantz rc2000) sending out the learned signal only turns on the projector 30% of the time (i have to push the button more than once to get it to work, so I still use the original seleco remote for controlling the projector)- theres something funny to these seleco remotes...
