so i always hear people talking about how great on demand is. i finally can access it on D*, but I don't understand the hype surrounding it. do my friends with cable get a much better experience? i know they can watch "instantly"(although with my internet connection there isn't a big delay after an initial buffer), but that isn't what confuses me. there is hardly any content unless you are buying a PPV movie or something. there is practically no HD content. the only way i could see it being useful is if you get something like HBO, but even then, only game of thrones seems to have all episodes available.
