DirecTV users tell us that the satellite provider has sent them an e-mail saying that effective April 15, DVR recordings of pay-per-view films will only be available for 24 hours after purchase.

Not exactly the smartest move from an industry that's keen to put a dent in piracy by offering a robust, consumer-friendly product. From DirecTV's website:For now, anyway. The entertainment industry has already derailed the concept of network DVRs, and would love a future where ad skipping simply isn't possible. Also in the name of "progress," users this week reported that HBO is now using DRM that prohibits TiVO users from watching certain shows more than once.
