Re-enter password almost every time (infuse / media player)


Almost every time I start Infuse (media-player) I get the following error:

“Could not open dir [smb://MYSHARE/…] Reason: no such file or directory (2).”

I have two “ATV 2”. One in my living room and the other in my bedroom. This happens to both of them. 

Usually I can fix the problem if I go to “Edit share” and re-enter the password. This works for a day or so and then I have to do this all over again.

Do you know what the problem is?
