Hi Guys this is a question i have been meaning to ask for a while.
Basically i have used a few media servers with the wdtv, from the one built into windows 7, xbmc, orb, tversity and playon.
My favourite of the lot has to the playon...you can download a free 14 day from here http://www.playon.tv/playon
Basically you install it on a pc in your network and you can stream from various sites to the wdtv. From Hulu, Pandora, Espn, Neflix etc etc.....you can also get additional plugin to add more streams than the offical built in ones eg you can get a bbc iplayer plugin, nbc, thecw etc etc
Now the really useful part is if you use a vpn eg the free hotspot shield http://hotspotshield.com
you don't have to be in the usa to get them to play on your wdtv....
Also as there is now a new free vpn for the uk from the same guys called expat shield http://www.expatshield.com
you can also stream uk geolocked program as well...(this is useful for any of you guys that want to watch any of the catch up tv from the uk, eg bbc iplayer or itv player) (unfortunately at the moment you cannot have both installed at the same time you have to install and reinstall which version you want uk or usa)
Now my 14 trial is long expired and i have been meaning to pay for the full version cost $79.99 as i find the program so useful.
However i was thinking that i wonder if anyone here was interested in building an external server for the wdtv ..a little like umsp but we can then add the streams we want to it...if this is not possible then i will go ahead and get the full version of playon, which i highly reccomend to anyone...
Btw i recommend a program called nevermiss.tv for a really nice gui for the uk catchup tv http://www.nevermiss.tv/
and Hulu desktop for the usa ones http://www.hulu.com/labs/hulu-desktop
Dont forget to have your vpn running when you install the programs....you can switch the vpn off when not needed
