(Does not work with) ...Comcast.
Oh well, Netflix works as does my Slingbox.
Can't speak to whether it works on the iPad, but it works quite well on my laptop via my Comcast subscription to HBO. There may be a couple of factors at work here.
First, you must have a subscription to HBO through your cable provider, as noted above. It's not a "free" service. Second, I'm not certain that all Comcast subscribers can access premium content (such as HBO) on devices other than their TV's. Here in the Seattle area, Comcast was re-branded as "Xfinity" when it began offering premium programming on wireless devices. If that is not yet a nationwide feature, you may not be able to access HBO or other premium content.
