Yum expert needed

[Karl Larsen <k5di@xxxxxxxxxx>]

   On FC6 we have been experimenting with versions of gstream software 
to get back to the performance of the Volume Control that FC6 had before 
Updating. I have found that the proper software can be obtained by yum 
install gstream.

   The problem is that the current rpm's loaded are of a later date. I 
want to load older rpm's on top of the ones on my computer now. Is there 
a way to do this?
