Hi all, I had this problem last night while watching Sundays recording of The Serpent, approx. 48 minutes into the playback the tv screen went blank and the blue light on the front of the Aura went off. After about 30 to 45 seconds the Aura blue light came on at full brightness then a reboot took place with the Humax logo and then Android logo showing. The tv came back on defaulting to a live tv channel, going back into the Serpent recording it had gone back to the start but I was able to return to the point where the box had crashed. I spoke to Sean at Humax and he said he and his colleagues had not heard of this problem since the release of the Aura and to monitor it and report back if it happens again which I will do. It would be interesting to know if anyone else had had a similar experience.
Had the Aura over two months now and have not had issue as you describe.
We watch between two and five recordings a day and also use the VLC player and it has been fine.
The only issue we have noticed is an odd pixilation picture break-up on some recordings even when the signal fault icon is not shown against the recording.
Hi davidrew, yeh it’s a queer one, I will just have to keep an eye on it. Other than that I’m quite happy with it.

To me that sounds as though the Humax software has crashed and caused a reboot. It has happened very occasionally (once or twice a year) on every PVR I have owned. If it reoccurs in the next few weeks then something is wrong; but if it is 6 months before you see a similar issue then write it off as one of those things that shouldn’t happen but does.
To be fair it did happen to me a few times with a HDR1000 while watching recordings, like you say all I can do is keep an eye on it.
This is a software fault which could be corrected.
My experience is playing back a recording which was recorded on a weak channel there is a blipp and the aura has lost its file locations and goes back to the beginning.
PS dont tell me my weak channel is my Arial. because the Tv plays the channel perfectly
and my computer with tuner fitted on the same Arial line is perfect.
So the aura tuner is weak.

Perhaps you could tell us the signal strength and quality on the channel in question? There are several other possible causes other than a weak signal.
When it happened on my Aura I was watching The Serpent which was recorded from BBC1 so that is a strong signal. The reading I get from the Pontop Pike TX for BBC1 is signal strengh 93% and quality 100%.
I have recorded dozens of programmes over the Xmas period. Apart from the slight glitch already mentioned had no reboots of any description.
Posts like my TV works means nothing. Tuners vary in sensitivity. The less sensitive ones are hard to overload. The aura however appears to have sensitive tuners. Contrary to what you might think too high a signal level can create a distorted output due to the peaks of the UHF carrier getting clipped. In this case you need to reduce the signal level not increase it.
Mine shows 92% quality 100% which may well the cause of the occasional glitches. Variable TV attenuators are widely available.
If your quality is fluctuating it’s a sure sign of too high a signal level
Professional installers should have an expensive spectrum analyser that has a oscilloscope screen that can clearly show that the sinusoidal analogue UHF carrier is missing the peaks. Without an accurate analogue carrier the tuners cannot create a accurate digital stream after the digital modulation is removed leaving just a stream of zeros and ones.
I don’t think signal strength has anything to do with the fault I stated, watching a recorded program and the box suddenly crashes surely has nothing to do with signal strength. Really losing patience with this box.

On what knowledge are you basing this post ? Any digital transmission requires synchronising with the frame synch 25/50Hz pulse data. If this lost due to to carrier distortion. It loses synch and of course it can cause a crash because it cannot find the data for the next frame.
Basically I have suggested a low cost fix. If you aren’t prepared to try it out stop wasting our time.
I repeat this is likely the cause. Your other box has exactly the same source.
Tuner overload remains the only possible cause unless you have a hard disk issue.
A PVR works by copying the digital data produced by the tuners as is to a hard disk. Provided the Hard disk is copying every bit to the hard disk. Replay should be identical unless of course the hard disk has bad sectors and is dropping content.
Does your box allow pausing of live content ? Does it also record the complete content of a programme you were watching when it started by simply pressing the instant recording button ?
Try a web search on carrier clipping in transistor amplifiers.
The other box was a Freesat box not Freeview, I’m not wasting anyone’s time that’s what forums are for, by the way your not related to Nigel Goodwin are you as he has the same attitude when answering posters.

Whether Freesat or Freeview makes no difference.
I have to ask what possible conclusion you are deriving from a freesat box using a dish receiving from a group of satellites more than 22000 mls away and a terrestrial transmitter a few miles away ?
All true pvrs work the same way.
Did you know you can get the Aura to record all 5 HD channels from the main PSB3-HD mux.
Not a feat your freesat box can emulate.
This happens to be a really good way of testing your box is working as it should.
If you are prepared to listen despite your posting I will post how to test this out.
Otherwise not going to waste my time anymore.
Try setting a Watch recording on any channel.
After the box switches the output to the channel you selected.
Press the instant record button. Do you get a recording you can view in the recording list and view from the beginning which continues to the end of the programme?
If not your box has a hardware fault. Possibly corrupted sectors on the hard disk used to store the recordings.
The same should also work on a G2 Freesat box but not a Foxsat-HDR
