Good morning.

Yesterday I increased a package in Polish Cyfra+ provider. Now I have a HD channels. All channels like: TVP HD, MTV HD, National Geografic HD, Eurosport HD, Europosrt 2 HD working good and smooth, except National Geografic Wild HD and Animal Planet HD. In this 2 channel I have big stuttering (if I use Cyberling 10 decoder) or green artefacts (if I use CoreAVC decoder or oryginal windows 7 decoder). I check few dllshowhelper and have this same problem. When I press Shift+1 a see a graph:
sharp green, red and yellow line and fresh rate changes between 28-50 fps. I check two defferent mediaportal (1.1.1 and 1.2.0 Alpha) - this same problem. I check a DVBViewer and working good too. I found at forum similar threed: https://forum.team-mediaportal.com/mediaportal-1-1-0-rc-3-6-519/some-tv-channels-stutter-heavily-look-flawed-82578/


I use MDAPI with Phoenix card reader. But decoding by thise plugin working good. I wrote to inifninte.loop and he agree to add this threed.

I add a logs with:
1 - only problematic HD channel (National Geografic Wild HD, and Animal Planet HD)
2 - with ok HD channel (National Geografic HD, TVP HD) and problematic HD channel (National Geografic Wild HD, and Animal Planet HD)

In my opinion at this problematic HD channel in log we have a "Video Continuity error... 1 ( prev e )" - demuxing problem.

Sorry for my English.

Hi there,

I thought video continuity errors were mainly down to poor signal. Have you rescanned the transponders/channels?

I know there have been threads by others with problems for those channels - But I don't think there was ever a obvious fix?

Have you tried using the MS DTV codec?

Have you tried disabling DXVA with PDVD?

Have you tried the latest PDVD codec?

Thanks,

J.

Yes i try rescan channel, I try codecs: MS DTV, ATI decoder, PDVD 9, 10, I try disable DXVA...still this same effects.
We have in Poland 3 providers: "N", "Cyfra+" and "Polsat Cyfrowy". Cyfra+ take some channels from "N" provider transponders. This channels are National Geografic Wild HD and Animal Planet HD and I have problem with this channels.

Have you disabled: MediaPortal Configuration -> TV -> TV Client -> General Settings -> TS Read Options "Don't drop...." ?

What happens when you record something on one of these channels and play the recorded *.ts file:

• inside Windows MediaPlayer
• inside MediaPortal -> MyVideos
• inside VLC

MediaPortal Configuration -> TV -> TV Client -> General Settings -> TS Read Options "Don't drop...." - i check enabled and disabled function. No change.

About recording... I open recorded movie only in mediaportal - recorded programs - I have big sttutering without artefacts.
I check today evening in windows mediaplayer and power dvd.

In my opinion at this problematic HD channel in log we have a "Video Continuity error... 1 ( prev e )" - demuxing problem.

Sounds liek a signal or tv server issue. Plase upload a sample .ts file.

Ok...later i add a sample *ts file. About signal: I have monoblock quad converter on my antena. I have connected 3 types of reciver: Opticum HD9500, HTPC and reciver from "N" provider. Only HTPC have problem with this 2 channels. Maybe Animal Planet HD and National Geografic Wild HD have a special transmission, structure or screen size.

Signal issue was my first guess, but he said in his PM that he has no problem watching the channels in question with an other TV Software.

@MacGyverek
Just for your information. If a channel works with a receiver, you can still have an signal issue with your TV-Card.
Depending on the quality of the tv-card, the cable used to connect it, etc, the signalstrenght can be a lot less there than on your receiver.
So only way to find out if it is MP or not is to use an other application. Which you have tested allready as you said.

My question is why only this channel...Germany HD channels on Astra workingt fine, a channels on Hoitbird too. Only channel on transponder 3 are problematic. Please see: Cyfra + on Hot Bird 9 at 13.0°E - LyngSat TP3 (freq 11258 H). Maybe this transponder have a poor signal??
