What happens is that the movie shows a rather noticeable grain in dark scenes, and also every second or so there's a frame that is different from the rest, a little brighter and grainier, which is probably where the change of GOP is located. Also, if I press pause, the frozen frame shows an excessive amount of grain, and advancing frame by frame looks, like there's a short flash every time I advance one frame. All the picture filters in the player are off.
Like I said, at first I thought it was a movie poorly encoded, but over time I noticed that most movies had this problem, and yesterday after watching "Super 8" exhibit the same problem, I took it out and put it in my older Panasonic DMP-BD65. I had written down a time in the movie where this was especially noticeable, which was minute 54 for the rest of that sequence.
Well, the Panasonic was perfect. No added grain, no noticeable change of GOP frame, and pressing pause doesn't turn the picture into a grainy mess. So that's when I realized, Sony really screwed up this player with the latest update, because I don't remember seeing this at all since I bought it until a few months ago. The Sony support page for this player shows the latest update is M03.R.769 from 6/28/11, however I think I probably got it around September because I don't have the player connected to the internet, I only connect it every few months in case there's a firmware update.
So what I would like to know is, is there a way to revert to an earlier firmware update, and if so, is there a repository where I can find them? The Sony website only seems to have the latest one. Or, is there a way to revert it to the factory firmware, or once the update is applied, I'm stuck with it?
Thanks
