According to Haas's book the seperation of A and B Zeta Oionis is only 2.6", so you could need a fairly high power to split. Her observation aws at 200x, so what Ep and power were you using?
The C star is only 8.5 mag but is nearly a full minute away.

While you are in that part of the sky, try out Iota Orionis, sep on that one is 11.3", so will give you a clearer idea of resolving power of your scope and EPs.
