The patch I posted in a previous message in this thread has a problem
and interferes with some other RealAudio formats. I have fixed this problem and
also adopted a better lost packet replacement which make the glitches less
audible (to my ears at least) and tidied up the code a bit.

I have posted the patch to the developer mailing list. Solving the problem 
with other RealAudio formats delayed this posting.
