Subtitles?

[mattd27]

I'm completing all my tutorial missions to unlock Sim mode, and about 5 or 6 missions through, I stop hearing my instructors voice, and I get these subtitles up on screen. I can't read them on my SDTV very well and it's really pissing me off.

I've checked the options menu like 5 times and the subtitles are definitely set to No. Any ideas? I hope it's just something stupid that I'm missing, and not a big problem.
