WDTV Live! iPlayer?...
As far as I know the WDTV Live! does NOT support iPlayer. It is a glaring omission in their line-up and a source of frustration to me (I own 2 of the devices).
It's a great box otherwise but this missing feature is such a pain that I am considering buying a different streamer since I can't get decent Freeview where I am but the broadband is good.
The WD forums are full of people screaming for iPlayer support but as of yet they're being ignored.
