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).
