I think its a bug with our remux code. Do you still have the wtv file for the example you posted in the first post?

Thanks. I have the file now if you want to take it offline.

I finally got a chance to look at this today. Unfortunately I can't reproduce the problem with the wtv you gave me. Can you post your serverwmc log on pastebin.com so that I can see if we have a difference in settings?

Sorry i didn't notice that you posted it already. Also, looking more carefully, I do see video corruption at the same time you reported it - it just doesn't look the same as the vid you posted earlier. So i have something to work with for now.

Hi, just wondered if you were able to make any progress on this? It happens so frequently that it makes certain types of programmes almost impossible to watch (typically news etc which contain lots of still frames).
Is there anything else I could do to help get to the bottom of this?
I've just installed 1226 and have tried every version in-between but always the same. I've tried two server PCs (one Windows 7 and one Windows 8), three different TV tuners (two PCIe quad DVB-T2 tuners and a USB DVB-T2 stick). Clients on Windows 7, 8, 10 & Raspberry Pi 2 (OpenELEC). Kodi Isengard betas through release and all five betas of Jarvis. I feel that I've eliminated everything that could be unique to my setup so am surprised it's not reported more often.
I'd really like to get this sorted so please do let me know if there's anything I can test or data I can provide (logs? examples etc?) if it would help?
Many thanks!

Actually I haven't forgotten this at all. This problem just turns out to be way more difficult then some of the more immediate stuff we wanted to change so it got relegated to the background. I thought I was clear earlier that it was a problem with our remux code, so trying lots on stuff on your end will likely not have any positive effect (however have you tried turning off hardware acceleration in kodi?). Part of the thing that makes this difficult is that what the problem looks like varies from player to player, and none of them look the same as what you posted in your video - for example vlc doesn't show any corruption at all.
While I know the problem is in our remuxer, figuring out what the actual cause is requires actual learning on my side and firing up more synapses then I am used to (hopefully they are still there). But as an interesting puzzle to work on, this one is at the top of my list, just a matter of finding time and ignoring the little bugs people keep finding. Its good to hear that someone still wants it solved.

Hi, thanks for the update I really appreciate the effort on this!
I was trying various things more by circumstance than anything (one tuner card died, I bought USB tuner sticks while waiting for RMA, replacement card was an updated model etc.). Really I just meant that if there's nothing unique about my setup why isn't the forum full of people reporting the same thing? It may be in part as you say it looks different on different systems (on my Raspberry Pi's it's not as noticeable but can cause it to rebuffer).
I did try disabling hardware acceleration in Kodi some time ago, my memory's a little fuzzy but from what I recall it still messed up but looked a bit different, I'll try it again and see.
I also thought it may be a UK based issue, I understand that the encoders used by the terrestrial broadcasters here are supposed to be extremely efficient, perhaps they use some obscure part of the DVB or H264 spec to minimize the datarate and give as much space to the other channels sharing the MUX. But hey I'm just guessing here I could be way off!
Anyway, thanks again, I'll keep my fingers crossed!

It definitely is broadcaster dependent and we did have one other user who complained of the same problem and he was also in the UK. It is curious that we don't have more, as we have a lot of users in the UK. Have you noticed whether the problem is only on certain channels?

Hi, I've noticed it mostly on the main HD channels here (BBC, ITV, Channel 4) which are all on the same MUX (PSB3) and thus encoded together. But that could be more down to the type of programmes that show it up being more common on those channels or simply the fact that we watch these the most (there are only two HD muxes anyway and I don't recall seeing it on SD channels).
HD is transmitted here using DVB-T2/H.264/1080i, SD is DVB-T/MPEG2/576i.
