The box has been working reasonably well (apart from gaps in recordings and displays of "The channel is scrambled or not available" and box freezing for a while) but we were living with it. Then on Sunday it stopped when playing back a recording and that was it! Could not play back any recordings, in fact they seem to disappeared and reappear after power cycling(sometimes there, sometimes not)! Could not record(always says 'less than 30 seconds recorded so may not be saved' and scheduled recordings not saved), or delete any recordings and when attempting to re-format the hard-drive it took almost 4 hours but all the folders were still there! Tried again with the same result. Also tried 'factory default' twice with no effect.
Phoned Humax today and they agreed to replace it (after the usual re-tuning suggestion). Hopefully it wont be the same as previously, i.e. no replacement and they eventually returned old box!!
I live in hope of a non faulty Humax PVR.
