i tried watching the Blu-ray version of 12 Rounds but was unable to get to the actual film. i just read that someone had a similar problem with their Pioneer 05Fd.
i can navigate menus and everything, but once i hit Play, it looks like it's going to the Main Title, but the screen goes black and stays there. the front panel of the OPPO stays on 00:00:00. i don't think there's a Title listed; if there is it's 0. i left it on for a few minutes before trying again and again, but all i got was the same result. i tried it with both the Unrated and Theatrical versions of the film, to no avail. i couldn't select a title to play either. i thought of watching a special feature and selecting a title from there but i forgot before leaving for work. btw, i won't be able to duplicate the problem as it was a Zip.ca disc and i sent it back earlier today. (no big loss with that film.) i thought i'd mention the problem here.
the disc is clean. i did notice a bump or two under the disc, very close to the centre ring; part of the melted coating. that could be it, but i'm going with the mastering of the Blu-ray.
