Video In the Movie??

I noticed the lead character is watching an adult movie very early in the film. You'll see the back of a redheaded girl about to go down on a guy. That is from the adult feature "Palace Of Pleasure" and Melissa Hill (from back) and Alex Sanders. I noticed that it is footage NOT actually in the video "Palace of Pleasure" or from the behind the scenes footage in "Deep Behind The Scenes With Seymore Butts 1". Anyone know how this un-released footage ended up in this movie. I thought maybe, while doing research for this film, the filmmakers may have visited the set of "Palace". Only thing is that adult feature was shot in December of '95 while this film is a '99 release. Maybe it was shot years before it's release-not unusual for an indie-???
