its not indemand ppv because comcast dont have indemand ppv in hd. they only have ondemand hd content.some you pay for some you dont. i prefer hd on demand then just hd channels because i like picking what i want to watch when i want to watch it instead of settleing for whats on the current hd channel at the time. but for old people i can see your point. older people have a harder time getting use to ondemand.
