Season 7 of Discovery's "Deadliest Catch" saw the return of the Cornelia Marie, but without her legendary captain, Phil Harris, who passed away during the filming of Season 6. Phil's sons Jake and Josh are back on the boat, but sailing with a new captain.

The season also introduced two brand new skippers -- Elliott Neese and Scott Campbell. There was plenty of drama.

The DVD has the entire season plus a "Behind the Scenes of Season 7" featurette, and a look at the "Best of Season 6."

And it can all be yours! Just send me an email by midnight tonight and you'll be entered in a random drawing for the 4-dvd set. Include your mailing address and we can get the DVD out to you quicker.

Good luck!

It's once again that time of year when I'm reminded of why I don't go into the ocean past my ankles: Shark Week.

Shark Week 2011 kicks off tonight on Discovery with Chief Shark Officer Andy Samberg ("Saturday Night Live") serving as host for the entire week.

Discovery is bringing back some old favorites for their 24th annual thrill-fest ("Top Five Eaten Alive," am I right?), but there are also seven brand new shark shows debuting this year.

Also, for the first time, Shark Week 2011 will feature live co-viewing for iPad, iPhone, and web users. Download the apps or be at the Shark Week website each night for three consecutive hours of interactive content designed to enhance your Shark Week TV viewing.

Things start tonight at 9 with one of Discovery's new programs. "Great White Invasion" is a chilling look at why great white sharks are suddenly being found swimming around surfers and vacationers from South Africa to Australia, and up and down the California coast. Why? WHY!? After that, another new show, "Jaws Comes Home," tells the story of shark expert Greg Skomal as he documents six months following five great whites with names like Curly and Ruthless. His mission is to understand more about their 1,200 mile journey up and down the eastern seaboard.

Check out the full Shark Week schedule at the official Shark Week website, where you can also view shark galleries and watch videos.

Get this. NBC is reporting that the bomb-strapped gunman who took hostages today at the Discovery Channel Headquarters got some bomb-making tips by watching the show "Mythbusters" -- which airs on Discovery.

NBC  had a ten-minute conversation with James Lee before police shot and killed him.

Discovery Communications operates the Discovery Channel, TLC, Animal Planet, Science Channel, and Planet Green networks.

James Lee, the guy who has taken hostages at the Discovery Channel today, has a crazy manifesto on his website, SavethePlanetProtest.com. The site has crashed today because of heavy traffic, but here's a cached version of his list of demands.

Lee is pictured here at a protest at Discovery Channel Headquarters in 2008.
