Also, while most servers disable TacView from working, you can always replay the saved track later with TacView running and it will record the replay.
Unfortunately if you have any hiccup in the track file, it might not work right. I don't know if DCS World fixed it, but it used to be unless you exited the server, you generated one looooooooooooooong track file with all your respawns in it, making playback a bit problematic unless you could just let the thing run for hours on end. >.<
