I checked that IheartJake.com still has the clip - and they do.
Go to that site's Media/Talkshows section and scroll down a little. There it is. I haven't checked whether it's available on Youtube, but I would be surprised if it isn't.
However, I realized - personally, I can't watch it yet. Not yet.
I remember how thrilled I was to see it back in the day though, because Jake was filming Zodiac, so he wasn't around for much of the publicity and I think Oprah was the first chance we had in forever of actually seeing Heath and Jake together; - promoting the film. And they sure looked good and seemed to enjoy each other's company.
