IR Remote Interference

Some people have been worried about IR interference that would occur if two teams picked the same IR codes. The chances of that happening are so low that I don't think it will ever happen, but I am worried about something else. I have been experimenting, and it turns out that if any two remotes are transmitting at the same time, neither of there codes will be received correctly. I have tested this with several combinations of TV remotes.

Understand that the IR board is not being triggered by other remote controls, but the presence of other IR transmissions causes the IR board to not react to the intended remote.

I am wondering what is going to happen when there are 6 remotes all going off at the same time and the IR lap counters are on, or when somebody realizes that they can cut off all communications with the other team's robots by holding down any button on their remote. I don't think I am going to be able to rely on the IR board to control the robot in the hybrid period.
