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.
