By the way I'm trying to stream a video file. Wasn't clear on that in the original post.
I'm currently trying to figure out how to stream to my LN52B750 model TV. I've tried the Samsung media center, the 'Play To' option through Windows 7, and the Media Center in Windows 7 itself. Can't seem to get any of it to work.
Does the file need to be a certain codec? As far as I can tell I've enabled all the options necessary in 7 to be able to stream, and my computer sees the TV, but it simply won't work. Anyone had any luck?
