I forgot to mention, that my unit has locked up twice on me in the last few days, requiring a plug pull to get it going again. First time it happened when I hit the update services button, and the second yesterday when trying to open Netflix. Hopefully it doesn't happen again.
On mine when watching a BD or 4k disc if I stop it (not pause) at times the unit freezes with a flashing home screen. If I disconnect the HDMI connection and then reconnect everything is fine, It does not happen if watching a regular DVD.
Only problem i have had so far.
