This might have been mentioned elsewhere, but according to the web page for Hulu Plus support for WDTV players is “Coming later this year.” They show a pic of the HUB, but since they say “players” (plural) I am guessing we will see the same functionality on the Live and Live Plus.
Well, for what it’s worth, on the Hulu website, it was “coming soon” last year as well.
As far as I know, WD added icons for it in the Firmware, to at least the Hub, quite some time ago.
Doubtful it’ll be on the Live (non plus) because that platform lacks the hardware to provide DRM.
