No, to me is sounds more like Real player's fault (
http://www.gnutellaforums.com/showth...threadid=28689 for an example of how "perfect" and "bug-less" Real is)
I will yet again make the, now old, suggestion to dld and use the free VLC player at
www.Videolan.org . You won't need more codecs than it already has.
And as another general suggestion, don't use Real that much: I hear it's not all that good.
