print,
Welcome to the forum.
The 6-Series plasma does not include DLNA functionality, and that's what the PC Share Manager software uses to connect to the television for DLNA functionality.
The PN50A650 won't recognize the software, or the connection for that purpose.
Let me know if you have any further questions.

Hello.
Just bought my plasma PN50A650,so new to forum. In my Samsung account page, I of course see the download page for firmware. In some other webb page pertaining to Samsung I saw the software called (PC Share Manager). I can not find this software download on my account page. I did find it after surfing the software words and samsung, but the software was listed for a different samsung tv. It's version (1.4.3)I have windows xp and vista. If I install it on my computer, will I be able to use it for my model tv? Or is it that my model tv dose not need it?
