I've tried it with the SW Blu Rays, and you can't even still step more than a few frames without the chapter/timeline thingy popping up, and you can't advance any further. About the only Blu I can even do that with was Metropolis, (the Moroder cut) and that may have something to do with the lack of Java crap on the disc.
DVD's on my Panasonic Blu Ray player have no such problems. In fact I can still/step backwards and forward better with it than my DVD player can.
