The "analysis" process does not begin until a VIDEO_TS folder is opened. I agree with Jethro and others that this must be some sort of system issue, or as I said earlier, maybe a software conflict. Make sure your HDD is not in PIO transfer mode. You might also try opening without a DVD in the drive and without pushing any buttons to get to Common Settings and disable the read ahead cache (and PathPlayer if you haven't tried that). I can't duplicate the problem.
