I recently updated the tv to firmware 65.10 and apart from the hdr in the menus while playing movies(grayed subs) i noticed that when i play a 4k high bit rate movie from usb 3.0 external disk in usb 3.0 port the movie freezes after playing normal for about 30-40 minutes an the only way to fix it is to restart the tv..this wasnt happening before the update

anyone else having this issue ? 

what is sony thinking without even testing the new firmware ? 

i am a bit dissapointed .also from the fact that it has only 2gb RAM but thats another story ...

any ideas ?
