We have just been trying to watch Harry Potter's latest, and made it as far as 1hr 30 mins. The film then corrupted and paused. On trying again, it would break up and skip back an hour.
Was this a dodgy download? No, it was a bought Blu-Ray

Is it my player? Doubtful every other disc has been OK.
If Warner Bros want to support this legislation agains piracy they could atleast make decent disc, even the last one seemed to give the player a bit of a headache trying to track the disc OK.
Edit: eventually saw the rest after pulling everything to pieces and plugging in my laptop which has blu ray and hdmi to the TV, even that struggled a couple of times.
