hi m8
ok i`m no techhead but after reading through loads of posts here and on the net this is how i got this setup.
pc to router-router to a cheap 5 port ethernet switch(this enables me to also add my 360 and later on sky+ box when anytime+ hits us)obviously dont need this box if you`re just connecting straight to sony system-ethernet switch to the bdv e870.
from there turn on pc and system.i`ve tried wmp11 and trial neorhome on the pc(tversity didnt show but i`m not sure on the settings for this).wmp11 seemed to work best with pictures mp3 and avi files.make sure that you allow wmp11 to see your device in the settings.
from here the sony picked up the pc no probs.all i need to do now is sort out the folders its see and manage my pc as i have files all over the place
on a side note can you access all the additional content when plugged in?bbc iplayer,love film,fifa etc just so we know that the net is working?
oh and while i`m writing this(i`m a bit scatty this morn

)did you "activate enhanced features" on the sony home page.sure i had to register then do a system update to get more features.just follow onscreen instructions.
let us know how you get on and sry i seem all over the place but my head dont function right at 1030 on a sat morn lol.any more q`s ill try and do my best to answer.
