Have you installed the PC Share Manager software from the Samsung.com/support site?
I cannot seem to be able to access my pictures/video/music on my Desktop PC from the Media Play button on my LN46B750. I am able to see and access them from my laptop which is on the network wirelessly, but not from the hardwired desktop. When I push the Media Play button, the only two devices listed are the "TV Memory" & the Networked Laptop, but not the wired PC from the router. I can't understand why it is picking up the laptop wirelessly through the router and not the wired Desktop. On the source button, the laptop is showing up under the DLNA position (I am not sure if yhis helps, but I thought I should list it).
Here are my specs:
Windows XP Media Center Edition SP 3 (connected from router with Ethernet cable)
Windows Vista Home Premium Media Center Edition SP 2 (connected to router wirelessly)
Linksys Wireless G Router (WRT54G2)
Samsung LN46B750 (connected from router with Ethernet cable)
I am able to get the widgets on the TV as well as the media from my laptop, just not from the desktop, so I am pretty sure the cable is fine going into the TV. I called Samsung and she said that it is not possible get the info from the desktop, which other than the fact that she was very nice, she seemed confused and mistaken on a few other areas that the TV could not do, that it was and is able to do, so I am in hopes of a better answer through this forum.
Please help.... this is driving me crazy because it should be so easy
