It already does that as long as the "iPlate" is on screen at the time. If it is not, just press "i" before pressing "Back".
It's way past too late for humax to pay any attention.
one thing I struggled with before buying a HDR-Fox T2, was the fact that it has no UHF modulator - I have solved this omission using an old VHS recorder's SCART to get an analogue UHF distribution around the house).
Of course! - Obvious! - How could I have missed that?
Was there another PVR on your possibles list which did offer a modulated output? I doubt it. My analogue PVR of (maybe) 10 years ago didn't have UHF output, and I used the same solution (still do).
"sarcasm"? - How dare you!
