I press after power on "Eject" I get example often the message "loading" * bssss * "No Disk" or the specialist goes on to immediately reach out again. In between, always an eternal "Loading".
Completely crazy!
When playing DVD come with me also on artifacts.
I had some years ago a Philips phone and that was just a pile of junk.
