One TiVo user captured a screenshot showing that Macrovision has enabled a "24 Hours to Watch" protocol on a rather benign movie. What this means for consumers is that once you've begun watching a movie that you've saved to your TiVo device, you have 24 hours to watch till your heart's content until the movie will become unplayable.
Macrovision has 3 known standards they flag TiVo recordings with, those being Copy Never which does not allow a flagged broadcast to be saved to the TiVo, 7 Day Unlimited which expire after 7 days, but can be watched as many times as the consumer wishes within that trial period or 7 day/24 Hours which only allow the content to be stored for 7 days and watched for 24 hours before your TiVo box self destructs in a firey mess within your entertainment center.
