Let us know how you get on with it
So the significant feedback on the T4-R I have to give is I have returned it. I haven't though excluded buying it again further down the line after it's evolved. I didn't want to get stuck with a box that just wasn't quite enough for me to live with if it didn't evolve.
There were a number of annoyances, some more challenging than others but the deal breaker for me was the picture quality was subtly but significantly less than on my TV tuner. I do have a high end Sony OLED so my TV tuner should be good, but my old Fox T2 picture was better than from the T4-R. It outputs at 4k by default and the picture has soft focus effects especially on motion. Changing the output to 1080p or 1080i to match Freeview broadcast HD is better but it still looks/feels like low bitrate video with simple panning motion. The grass on football is not right and smears. It looks great when static. For live pause (one of my main reasons for wanting to replace the Fox T2) to be useful you have to be watching on the HDR full-time, and I can't face doing that on the T4-R.
Other than PQ:
It initially didn't start recording at the scheduled times properly, though this improved over the 2 weeks use.
It can be slow to respond to the remote at times.
The time bar for playback or live pause lacks time clarity e.g. how far behind live you are.
When browsing the guide, the guide moves behind a stationary cursor instead of the cursor moving across the guide and that really doesn't work for me at all
The TV guide search function is not in the guide but in the home screen which is annoying.
The information bar at the bottom of the screen is too dark and too high obstructing too much of the screen and stays on during FF and RW so you can't see where the programme is up to very well. The options to make menus more translucent do not impact the information bar which is opaque until the very top then grades itself a little.
Having been a Fox T2 user the way to select a programme to record (press record not OK) is frustrating but you would adapt to.
It just doesn't feel premium like the Fox T2 did. E.g general appearance , speed of response, no inset video in the TV guide.
My views and others may differ, but I hope that helps.
