Always check that post for Samsung owners in the CNET Networking Forum.
Remember that all these services break on all boxes and confuse the consumers when it works on the PC. (Why? Because they use other servers for tvs, etc.)
Ok, be sure the router firewall is off and put the TV into the DMZ. (ask the router maker how if need be.)
I have the HT-BD1250 purchased in 2009 at which time I activated Blockbuster for streaming. I've only used it a handful of times in the past, but recently have wanted to use it more and more. Yet, when I try to connect, I always get the error message, "We're sorry. We cannot connect to the network. Please try again later."
I can stream Netflix, Pandora, and YouTube just fine. Blockbuster? Not a bit. Oh, and I'm trying them all in the same sitting. My Network Connection Test comes up fast and solid.
I'm on WiFi and I cannot hook it up to a LAN seeing as my modem and router are in another room entirely (not close).
This is frustrating because Netflix's selection blows, so I'd like to be able to buy movies from Blockbuster for streaming as I desire.
