ive had a Samsung BD-h5100 that ive been using for more than a year and recently it started responding late to the remote in the middle of a movie file i play on via USB. And even if i don't touch the remote the subtitles even start to lag or delay a lot, audio goes out of sync with the video, audio goes mute for a short time, when the video info displays due to me pressing the button for it on the remote like 10 minutes or so earlier, not all the details display properly: like just the timer (not showing current time of the video)will show up without the full name and time/seeking bar of the video file . Plus the buttons on the DvD player itself don't respond. I have to switch the main power off to reset it. When i play the video file again the same problem occurs again even with a different video file.
