I have the exact same problem, except I am trying to connect to my Samsung Q45 laptop! We have double-checked the shared folders, tried creating a new user account on the laptop just for the HT-BD7200, no luck. Thought it was the firewall on the laptop, but even disabling the firewall makes no difference at all.
Would love to know if anyone has had success with this.
I just bought the Home Cinema system Samsung HT-DB7200 and I was trying to connect it with my iMac (OSX 10.6.2).
I mean, I perform an automatic search of the network on my Samsung device and it finds my iMac, then when I select the iMac it asks me to enter my User first and then my password but every time it doesn't link to it saying that the Username or Password are incorrect!
Is there something wrong in the steps I perform?
Is anybody able to help me?
