Palace boss Ian Holloway copped a touchline ban after blasting the dubious penalty decision in their 1-0 opening-day defeat against Tottenham.
And the Eagles were on the wrong end of another debatable spot-kick at Manchester United last Saturday.
Palace skipper Jedinak said: "We have been frustrated with what has gone on so far.
"It has been hard for us to get any momentum going. Every decision in the Premier League is heavily scrutinised and that's what we are now finding out. We don't feel like we have enjoyed the rub of the green.
"But it is important we do not dwell on anything or feel sorry for ourselves as we have had a tough run of games."
