IPmc would be useful for sports, news, and other live events. Think about how many people sit around their TVs staring at such things; it's probably a significant fraction of all TV-watching time. Better yet, folks who want to watch particular sports games will be concentrated in the two cities that are playing (i.e. high fanout at the bottom of the tree), which multicast delivery excels at compared to unicast.
For non-live content, even if one assumes people want their next episode of "24" on demand, wouldn't it make more sense to multicast it to STBs that are set to record it (or that predict their owners will want to see it), vs. using P2P or direct download? That'll save you gobs and gobs of bandwidth _immediately following the new program's release_. After that majority of viewers get their copy, you can transition the program to another system (e.g. P2P) that is more amenable to on-demand downloading of "old" content.
Of course, this is a pointless discussion since residential multicast is virtually non-existent today, and there's no sign of it being imminent. Anyone want to take bets on whether IPmc or IPv6 shows up first? ;-)
