I have tweaked the existing Sony TV (DLNA 16:9 1920x1080) cfg file so that it works with the US Sony Bravia KDL-46XBR9. I can't tell you if it will work with other members of the XBR lineup since I don't have access, but I feel that it more than likely would. It plays videos perfectly, even in 1920x1080 resolution, and I have yet to find any problems with playback of movies or music. I do not use Internet TV or Radio but if someone would like to take the time to show me what to download I'll be glad to test it against the TV.
My server is running on a P4 Quad, Oc'd to 3.4ghz with 2Gb RAM and a wireless N network and like I said, I've experienced no problems.
