I am new to the Zidoo hardware and it's possible that I am doing something wrong. Having said that, here is what I am experiencing. I was playing Harry Potter and the Sorcerer's Stone (Blu-Ray not UHD) and it was playing fine. I paused the movie for a few minutes and when I came back and unpaused the movie it was stuttering/juddering (not sure what the difference is). When I looked at the display screen with the particulars of the movie it showed that the video was changed to HDR10+. It was not that way when I initially started playing the movie. I refreshed the metadata for the movie which then showed correctly and the movie played correctly after that point. Has anyone else experienced anything like this? Could I have somehow caused this problem? I have also noticed that if I have a Blu-Ray version of a movie and a UHD version of the movie there doesn't seem to be any separate recognition by HT4? as to which movie is being played. What I mean is, if I play the Blu-Ray for say 10 minutes and then stop it, if I then play the UHD version it picks up from where the Blu-Ray left off. Is this normal behavior? In the past when I've used Kodi this does not occur.
