Hello,

Well I don't know if this problem has been solved yet, but for frequency 
format changing, I think that you would know NOT to do a direct convert.  
That is, I hope you don't just change the frequency setting and call it a 
day.  There are two ways to handle this.  1) resample it, most software has 
this feature.  2) use a track software to create a new file.  In away this 
is resampling on another level.  you can download a free copy of acid music 
at www.acidplanet.com if you don't have some of this software alread.  Just 
place it as a track in the program and save it within the loop.

Hope this helped, although it may be a weird way of doing things it works 
for me =)

G'day
