Perhaps.  I was running SVN and Fedora 8 X64.  May audio/video related 
drops and high load.  So much that I had to go back to the old stable 
rpm version. ( which works perfectly BTW ) 
Something is wrong in the SVN with Internal player and sound/video high 
load. Just my opinion.  Supported by many reports of issues here in the 
forum.
