    Another Aura recording which appears OK on the Aura is The IT Crowd, but on the PC played after downloading to my NAS drive had an audio delay – using MediaInfo (amazing utility!) it shows the Delay as 1 s 720 ms

    Also the same delay if played back on the Aura using Kodi

    That delay of “1 S 720 ms” is listed in your MediaInfo text for the subtitles.

    The main audio track is listed as having a delay of -374 ms.

    I need to see the full Mediainfo text. Particulary the video codec used to compress the video.

    Why do you think what Lefteris has posted is not “full”?

    For some reason I got nothing. I have it open now. The audio delay looks to be way too short. I would expect to hear the audio around 1 second before mouth movements.

    Sorry about confusion over delays – Can I do anything about that short delay ? I have tried increasing it in Aura settings, but it made it worse

    I would add that playing the same video on my FVP5000 or an old Panasonic box I’ve got – it is in perfect sync !

    If a FVP-5000T can play it back it should play back OK on the Aura. Have you tried installing plex on a PC and streaming to Plex on the aura from a file on the pc or on a usb drive connected to the PC.

    Have to confess, I haven’t ever got on very well with Plex – a 73 year old brain is not the best with some software ! Anyway, I’ll give it a go – I have installed the Plex app on the Aura, but I read somewhere on a forum about the Aura that a much later version of Plex is best for the Aura. Do you know about this, or was it a senior moment creeping in ?

    The plex version is the same as I have on a Amazon Firestick.

    I am 76. On the firestick it supports framerate matching but not on the Aura for some reason. This will not affect audio. Panning shots can look jerky which doesn’t happen on the firestick.

    Has anyone tried sideloading VLC on the aura. ?

    There lots of help on line.

    I have VLC on the Aura – is ‘sideloading’ different from the normal APPS ?

    I couldn’t find it. Does that not play the video if you stick it on a usb stick ?

    On a different tack I just recorded Father Brown on Freesat to confirm it has 5.1 surround.

    I had VLC all along just never used it.

    The file plays in perfect lip synch but only in 2.0 stereo. It’s HD 1080p incidentally.

    Try your errant file.

    I’ve attached an external USB drive to the Aura and selected a video at random and the same delayed audio is there as playing from Kodi. As I mentioned above, the VLC for Android does not have the extensive options for adjusting things like lip sync, unless it’s hidden somewhere I can’t find – the audio output options are just Audio Track or OpenSL ES – whatever that is !

    Whatever is happening, the Aura just does not appear to function as able to play back pre-recorded items from a different Humax device – nice interface with all the added features neatly laid out, etc etc – but if it can’t easily play other videos from a network connected storage as it claims, it’s not going to do me any good. For all its sluggish behaviour, the FVP5000 or even an HDR-Fox (if I could find a working one) is far superior

    Sorry – only just seen your latest post – I’ll check the Stereo thing

    Changed the Aura Setting from Surround to Stereo (2.0 not actually in the name!) and it makes no difference – in fact it looks a little worse.

    I had previously changed that setting from something someone else had said, and I’m sure I didn’t change it back to Surround. There are other settings as well like padding time which have reverted to defaults after the Aura has been switched Off and On again. Is that usual or am I getting paranoid ?

    What other Humax device are you getting the recording files from and how ?

    OK – I started with a 9200 over 10 years ago (using Cute FTP to download its files), then upgraded to the HDR-Fox T2. One was destroyed by lightning when our house burnt down in 2014, so I replaced it and when that gave up the ghost, I got another – all using the replacement Custom Firmware from Hummy.tv. Then a couple of years ago, when my final HDR was giving problems, I got the FVP5000, which I got used to eventually and am very happy with – I download the videos I record using Windows Media Player and saving them through Firefox. The reason I started saving videos was that we have had a small village house in Greece for some years, and since retirement we are able to spend more time there. So although going to the local ouzeries is our favourite evening pastime, sometimes the weather (particularly in winter) means we stay in, and the need to be able to watch stuff we can understand (Greek is not easy to follow) I needed videos I could transport and watch in Greece ! I am historically an accountant/business administrator, so my technical knowledge of things video is very limited. But I try and was hoping the Aura would be the next step up …. Watch this space ! PS – we used to play badminton in Devizes with a couple who I believe knew you – sorry can’t remember their names.

    PPS – FX on the Aura is a very easy way (once you learn how) to download recorded videos to a PC !

    I would love to know how you managed to use an FTP client with a box that doesn’t have an FTP server on it.
