Pixelation on HD Channels

Hi,

I am getting very bad pixelation on HD Channels, the SD are fine.

Sometimes you can go a couple of mins without distortion.

Sometimes the buffering box appears for a short while too.

Argus is running on a i5 with 8GB ram, a digital devices Cine C/T and windows 7.

This aerial is fine as when I plug into my TV the HD picture is very clear and stable.

The frequency is set correctly for BBC HD channels

The fontend is Kodi 15.2 Isengard
The backend Argus TV 2.3

I have tested on a different PC running Kodi and same issue.

Any Ideas?

Thank you

Do you monitor your own forum posts?

What graphics card are you using?

I had/have similar problems with Kodi (with DVBlink as backend, but I suspect that does not make musch difference).

I have Intel integrated graphics and I found out that Intel had released a new driver for it. Windows did not yet know about it. This was a huge improvement, but the problem did not go away completely.

Another possibility is increasing the cachelevel in Kodi: viewtopic.php?f=63&t=6687&p=37169&hilit ... ngs#p37169

Did you check your antenne cabling?

Well, both DVBlink and Argus TV report 100% signal strength and 100% signal quality during scanning. Also, my previous tuner, a SAB Unix triple has no problems (actually, a lot of problems, but not with signal strength and quality)

So I am inclined to believe that my dish/LNB's/cabling is OK.

But I certainly like to hear it if I am missing something!

Sounds logical that cabling should not be an issue.
Since introduction of 4g cellular we've seen more issues. Therefore cabling could be issue.

Other things like drivers CPU utilization, have you checked these?

I do not know how much of an issue that can be with satellite, but with cable, the signal can be too strong.

I have a Digital Devices card and a Y Split an 10m between the outlet an the card. There was an Amplifier between card an outlet and all was well.

Then the cable company tinkered with the signal strenght and the signal was too strong, wich resulted in very much the same errors as too weak signal. Removing the amplifier helped and all is well again.

Sorry that I did not respond sooner. But the problem went away by itself. Of course, I should expect it to come back, but until this day, it has not.

The CPU utilization is normally around 30%. I don't know what part drivers take of that.

There is no external amplifier which can be taken out. During channel search, the software reports 100% signal strength and also 100% signal quality.
