MINUS
----------
Together with Panasonic 46 inch plasma TV is unsatisfactory.
DVDs work as expected. See DVD - Watch TV - DVD look further.
For BluRay self is the torment. From the pause mode, no continuation is possible.
Standard scenario: View BluRay - briefly to the news (weather OAE), further see BluRay
= Disaster: TV without sound, Bluray starts right from the start - not a sequel.
For movies 50 years-James Bond Collection and Karl May collection device crashed repeatedly again and took no commands from the remote control.
It was up and running again only by Stromlosmachen.
Reading of BD and DVD lasts at least 10 seconds - up to 20 seconds for DVD, infinity (crash) for BluRay.
I've waited patiently these times and not the device irritated by multiple keystrokes. (Always with the user manual from the Internet on the iPad in hand)
A complaint at a regional and supra-regional Panasonic dealer took 3 months, and device came with the same error back.
Whirring sounds I could not perceive during operation.
PLUS
+++++
The sound is very good.
The pairing of the wireless rear speakers is unproblematic.
Manufacturer homepage is clear: easy to find instructions.
I trade to the device and can only warn against buying.
