I found the links privided by Niels Mayer quite useful on this topic:

http://en.wikipedia.org/wiki/Nyquist_frequency#The_aliasing_problem
Based on my own experience, it certainly happens, though I can't say

why, it may be resampling or crappy hardware as others pointed, but the

distortion is there and audible. It becomes impossible to notice with

high sampling rate recordings (at least on PC hardware, have not tried

on portable players yet).
Maybe it can be avoided somehow, but disk space is cheap nowadays so I

find more convenient to just record at 96Khz and avoid headaches.
