No, the LN46B640 does not have DLNA. I apologize for the confusion. The website is incorrect, and I will request that be fixed as soon as possible.
I just purchased the Samsung LN46B640 LCD HDTV last week and one of the reasons was for its DLNA support. Samsung's web page for this model at:
lists that DLNA is supported. However, I cannot get it to work. DLNA works fine with other DLNA-enabled devices in my home network. After doing some more research online, I have found conflicting information suggesting that DLNA is not supported on this model.
So, is DLNA supported on the LN46B640?
