Violence on TV programs for toddlers

I cannot help wondering whether the "violence" depicted on channels like CBeebies (BBC) is having a bad influence on toddlers? Violence is an extreme word but I feel the following content could be misconstrued by the toddlers:

• generally unpleasant behaviour in Higgledy House.
• Mud fight in Bob the Builder.
  

You may disagree with my view but I have evidence of such behaviour in the playground. My daughter has been pushed and hit by other toddlers just for being there. I cannot understand how toddlers can develop these tendencies. I am sure that there are cases due to the innate disposition of the child but surely the TV can be blamed for the quantity of violence in the playground?
