I purchased a Sony DMX-NV1, an excellent accessory for internet reception directly into the tv, without having the computer in the loop, but it is limited to what is available via Sony's programming. If I want to watch something via my PC, the DMX-NV1 has a "Send from PC to TV" feature, which backfeeds the signal, via my wired router to the tv. (Remember the router is carrying data both ways on the PC port.)
The Sony-supplied instructions with respect to the PC setup are sketchy, they speak of "XAMPP" and some other programs I need -- the ReadMe speaks in terms I don't understand, or assumes that steps omitted are "known by everybody"?!
