When he debuted his company’s new DVD copier at DEMOfall recently, called RealDVD, RealNetworks’ Rob Glaser did a video interview with BoomTown about it.

And now that RealNetworks (RNWK) and Hollywood are cross-suing each other over RealDVD–in the latest clash over the still-contentious copyright issue that separates the tech and entertainment industries–it’s time for a replay!

The RealDVD software allows a user to rip all the parts of a DVD, including cover art, onto a computer. It costs about $30.

Hollywood studios, which filed a lawsuit in federal court Tuesday, maintain that RealDVD is illegal, and one of their reps called it “StealDVD.”

Haw, haw. This is what apparently passes for clever in Hollywood these days.

But before the entertainment giants’ lawsuit, RealNetworks filed its own suit, claiming it was protecting the fair-use rights of consumers to make copies of content they had purchased.

To avoid violating digital rights management schemes, RealDVD has added its own DRM layer, preventing ripped DVDs from being copied and shared and imposing further barriers to piracy.

But there are still possibilities for illegal ripping, of course, because RealDVD users must promise not to copy videos they don’t own.

No surprise–an honor-system product that makes it even easier to copy DVDs was not exactly welcome by Hollywood, which has been trying to protect its movie revenues from suffering the same fate as the music industry via rampant CD-ripping.

Thus, the typical mainstream media reaction to the inevitability of consumers wanting to digitize content: More lawsuits!

In any case, here’s the video of Glaser talking about RealDVD:

“RealNetworks took this legal action to protect consumers’ ability to exercise their fair-use rights for their purchased DVDs,” the company said in a statement. “We are disappointed that the movie industry is following in the footsteps of the music industry and trying to shut down advances in technology rather than embracing changes that provide consumers with more value and flexibility for their purchases. For nearly 15 years RealNetworks has created innovative products that are fully legal, great for consumers, and respectful of the legitimate interests of content creators and rights holders. RealDVD follows in that tradition. We expect to successfully defend our right to make RealDVD available to consumers and consumers’ rights to use it.”

We’ll see, I guess. Clearly the silly little “RealDVD is for saving a DVD you own” disclaimer attached to the software isn’t going to cut it with Hollywood. I imagine we’ll be hearing from the Motion Picture Association of America before the day is out.
