Yeah, lingering and concentration effects are checked for Spell Resistance once, instantaneous spells are checked every time you cast.
If you cast magic missile and it fails, next round you can cast it again with a new SR check. If you cast magic missile and it's successful, next round you can cast it again but it still needs an SR check the second time you cast it.
If you cast telekinetic maneuver, which is a concentration spell, you do ONE SR check, and then the power lasts for 8 rounds (or however many rounds based upon level). If your initial check succeeds, it affects the target for the duration of the spell. Likewise, if you fail, it does not affect that creature for the duration of the spell.
However, if your battle goes long enough to warrant casting a second iteration of Telekinetic Maneuver, you would still do another initial SR check this time as well.
Hope that helps.
So what happens with something like call lighting or aggressive thundercloud which has a repeat roll?
