Buddie, i know what you meaning, what you want, because i want do the same, so here are my suggestion:
Get Fraps, enter in CrossFire, go to your Storage, there has an button "Replay" in the top of Storage, you click there and Open the Saved Replay you want, will start the whole game you Record, just start Recording with Fraps the Replay, move the cameras like you want, and after this edit the video with some Video Editor like Sony Vegas...
It's the only way you can record Replays, and yes, .cfr ARE CrossFire Replay, is a file of the game, can't be changed by a Converter. If you want record real play, you need to get Fraps and record the Game you ARE playing, without saving thing.
Hope it help, if not, just sorry
Ps: Fraps is the only program you can Record good games, all kind of videos on YouTube about Crossfire was recorded by Fraps! You can change the FPS on the program
