Comment 11 for bug 84729

I wanted to comment again on this bug should anyone with this problem stumble upon this hoping for a solution. Although it should be obvious to veteran Linux users, the problem is alleviated by mounting the samba/cifs share directly. That is, instead of navigating to the share through nautilus:

smb://hostname/sharename

then streaming the media from there, mount it using mount.smb or mount.cifs:

mount -t cifs //hostname/sharename /localfilesystem/mountpoint -o user=shareuser,password=sharepass

Streaming media from a share mounted like this totally eliminates the problem for me. Hope this helps someone else out there.
