What's the best way to remove wallpaper from the 1940's from a plaster wall?

I would like to remove some ugly old wallpaper and repaint. I'm afraid to paint over the wallpaper, I'd rather strip it that risk having it bubble and mess with the removal process later. I tried DIF on a different wall, and it only worked because of the shear amount of pressure I used and it took forever. Is there any products that can remove the old style wallpaper and adhesives from plaster walls easily? This wallpaper is still well attached with only very minimal peeling along the seems.
