I've noticed this strange behavior a couple of times when using the TiVo Unified Search to find movies. In this particular case a search for the 2011 movie, The Help, provides this result. When I click through to the HD option ($2.99), I see this. However, when I select <rent this movie> the price changes to $4.99. If I go back, the price on the previous screen is updated to $4.99. If you go into the movie directly through Amazon the price is $4.99 all the time. This appears to be some sort of weird database issue but its pretty annoying.
