Audio pops/clicks only during Ch4 News and Weather (2 Viewers)

[elliottmc]

He did say it also does it on ch 4, so would it not be the same?

Yes, you're right - doveman did say that. I guess my logic doesn't make a whole lot of sense.
Still, not being in the UK I don't know what the broadcast format for Ch 4 is - could somebody humour me and relieve my curiosity. All I want to know is whether it is 1080i or 720p... or whatever it is...

Judging by the bit rate and resolution (544x576i), the Channel 4 +1 sample posted in the OP must be captured from Freeview (DVB-T). Channel 4 on DVB-T is 704x576i.

Would be interesting if this happened on the satellite version of the channels or Channel 4 HD too.

 

[doveman]

Yes, it's Freeview. I don't have HD or satellite though, so I can't check this myself.

I think this problem might have stopped now actually, which may be thanks to 1.3 alpha. I recall watching the programme recently and it not having this problem anyway, although I think I only watched it once so I need to check it every night for a few days before I can say either way.

I've switched to my Main HTPC system at the moment and I'm getting this popping/clicking on Ch.4 News again. It might be a bit less frequent than before though, although it's hard to say.

Did anybody else watch the news to check this?
Given that I live on the other side of the world with no access to this channel, my hands are obviously a bit tied when it comes to trying to reproduce this problem.

Hi,
I have look the recorded sample (but i can't test live TV, it's DVB-T channel) and i can see the the same image like jump and we can hear click (iirc) i do the test with lav splitter too and under graphstudio.

As the issue is present in .ts file itself (other players behave in same way as MediaPortal) we have few possible sources for the issue:

1) TsWriter corrupts the specific channel (please test with some other DVB program to be sure)
2) Broadcaster encodes a broken stream

Thanks Seb
I think the next step is that we need test results for the live stream with a 3rd party application such as VLC to eliminate TsWriter as the cause.
@doveman: are you able to do this?

mm
[edit: tourettes was obviously thinking the same as me! ]

I've used MPC-HC to play LiveTV before but would VLC be better for this test? I'd also want to record it I guess so that I can upload it if necessary and I'm not sure if either MPC-HC or VLC will let me record, so could advise on that please?

I have licensed dvbviewer version but i think you can try a trial version

But you can't record with it but you can see if you hear/see the issue
