Well, number two son (IT apprentice) and I had a bit of a discussion.
He said that it would be better to buy a new TV than mess about with a separate unit attached to the existing TV. But my Mum wouldn't have any of it even after he offered to buy it for her (lovely gesture).
She decided she did not want the record facility as much as she thought, so we went for the Roku Streambar.
Me and number 2 went round today (her 85th birthday) and set it up for her. It's very impressive for the price (just under a ton).
Just a couple of niggles.
While the voice operation works well, the button has a magnifying glass on it, not the more intuitive microphone symbol.
Also, when you try and search for a programme to watch, it comes back with "not found". You have to use the remote to enter each app's search facility THEN the unit will allow you to use the voice operation to search for the programme.
If you want to watch a current broadcast, you can switch back to the TV by pressing the TV button on the Panasonic remote. Then back to Roku by pressing any button on the Roku remote. But it doesn't go back to where you were (ie in the middle of watching catch-up), it goes back to the home screen.
The other niggle with searching is that if you are in the iPlayer app and search for something you know is a Beeb programme, if another platform is offering it at a cost, the system will leave iPlayer, search, give you the options, then re-load iPlayer when you choose the free option. Bit long-winded and not intuitive.
The speakers are very good, throwing the sound out to my Mum, who sits about 10 feet away. Haven't found out yet, but it seems either that the unit will mute the volume during ads or you can set it to do so.
It attaches to the TV via an HDMI ARC port, although there is an optical cable bundled if your TV does not have an ARC port.
Be nice to go back and get better acquainted, then I can teach Mum a bit more about how to use it
The more she can do with her voice, the better.
In this regard, the Roku is a better choice, as, according to reviews, more can be done with Roku via voice commands that using the Humax Aura.
Left her with a box set of boney programmes to watch on iPlayer.
Will try to remember to update here when I have done more with the box.
