For those that haven't used it before, TeamSpeak Overlay is an add-on app that puts an interface on the left side of your screen to show who is speaking in channel when their mic is hot. It's great for TS comms, especially when the speaker is trying to relay battlefield intel.

TSO works great with OFPDR. I've been using it for about a month now without problem.

Here is a link to the TSO website.

I'm on Vista64 and run TSO in WindowsXP compatibility mode. Just turn it on before you start the game, and you're in business!
