How would one compare this to the Roku in the FP in terms of channel wise? Seems like the roku has additional channels to support tv and such.
Thumb rule is:
Roku is for more online streaming. It has more online channels (free & subscription based)
WD TV Live has limited channels. However it can play most formats of local media files.
also, consider this:
Roku doesn't support Youtube and Spotify whereas WD TV Live supports it
WD TV Live doesn't support Amazon video whereas Roku supports it
Both units support Netflix, HuluPlus and Pandora.
