You need to bouce to 44.1k, whihc is the sample rate of standard cd's. if you're getting distortion when you bounce to disc, you're overloading the master buss. Lower your track levels before bouncing, put a limiter on the master buss, and keep those levels down. Once you bounce to disc, simply burn from your comuters burner using Nero or other CD burning software, at no more than 4x burn speed, and I recommend 1x. the result will not be as loud as a commerical CD because it is not mastered, and while you can achieve some decent mastering results in protools, it does not equate to what a professional mastering engineer and facility can do. Hope this is helpful.
