But maybe the MPAA isn't misunderstanding, perhaps they don't like the fact that a cable subscriber could use DVR functions through their standard cable box without having to go through the trouble of swapping out for a DVR box. Thus making millions of new time-shifters without much trouble.
The MPAA fully understands.
They have been crying ever since the Sony Betamax case that went all the way to the Supreme Court. They oppose the VCR because they can't control what people record. The whole idea of "time-shifting" is something they view as lost revenue. Jack Valenti is still hopping mad about the whole thing.
