I was hoping someone with a little more knowhow would help you. The error user_xattr has something to do with your file system as best I can figure. Maybe you didn't mount a drive, or the netflix wants to use a drive and since silverlight is some bastardized MS code it wants samba, is samba installed? The error means something wants rights to the file system, exactly what I don't know. You apparently must have figured a solution by now, it would be nice if you could post what it was.
You have your way. I have my way. As for the right way, the correct way, and the only way, it does not exist.”
