When Dean recorded HBO’s new Tom Hanks-produced miniseries “John Adams”—which is not a pay-per-view or on-demand program—he was surprised to see it was flagged by Tivo’s Macrovision software, which controls how many times you may watch a program and how long you can store it before it’s automatically deleted. Now the question is, was this a mistake on the part of HBO or Dean’s cable provider Comcast? Or—considering HBO’s infamous anti-consumer stance on time-shifted programming—is it the beginning of a sneaky “back-door” approach to locking down all their content, something Tivo’s own people said would probably not happen when they added Macrovision to their recorders in 2004?
