What "we think" DirecTV should do, doesn't mean anything at the end of the day.
It may not mean anything today, tomorrow or even next year. Depending on how many people share this view, however, it could have a long-term negative effect on DirecTV's subscriber base and retention rate.
Companies that don't pay attention to what customers want (and are going to competitors to get) eventually shrink or die. Blockbuster, GM and Circuit City are examples of once dominant companies downsized or eliminated due to this. Ironically, major Cable TV companies are still trying to recover from the same mistake: In the infancy of both DirecTV and Dish, cable companies saw satellite as the alternative of last resort for hicks who couldn't get cable service. It wasn't until cable guys did a few million disconnects on homes with new grey frisbees on the roof that they figured it out.
Streaming, downloading and file sharing (legal or illegal) are reaching a quality, quantity and ease of use on par with satellite. How long it takes DirecTV to realize this will impact their profit (or loss) in years to come.
"Bit for Bit" HD copying seems to be the holy grail to Hollywood.
What I'm ranting for is copy protected bit for bit copying. "Holy Grail?" Bit for bit copying is more like a drinking fountain: BitTorrent, eDonkey and hundreds of other sites offer anything and everything digital. Based on the small number of lawsuits filed against home users for copyright infringement, it appears tens of millions of P2P/torrent users feel comfortable with the risk every day.
I think Hollywood already knows copy protection is a dead horse. The decline in prices of DVDs and Blu-Ray Discs, the free "digital copy" included with most DVD purchases and even PPV DirecTV movies available on the same day as retail release are proof of this.
Without endorsing or providing a "how to" guide, I'll just state the facts: "Hackware" (although possibly illegal) is available for any DVR connected to a home network; removal of the internal HDD is not required. If Hollywood and DirecTV want to make such activity less tempting, a simple and legal licensed backup method might just do the trick.
