Hi, I have problems with watching HD channels. I can tune them, but when I open preview in TvServer Cfg, I have only black screen and no audio (the same in MP). If I look at graph, the live1-0.ts.tsbuffer reports 1440x544, 0bits for video and 48KHz 0bit for audio. In original SW from KWorld I can see the HD channels.

What decoder is shown on the graph?

it was ffdshow. But in MP I've tried both coreavc and ffdshow without any success. In the ffdshow in the info page it does not show any info about the input stream. Is it normal, that the live1-0.ts.tsbuffer reports 0bit?

I suppose that the TV server builds another graph to receive data from TV card. Is this true? I cannot see it in graphedit.

Update: Just yesterday I noticed, that I can hear audio on one of the two channels, but still no video.

I'm not sure what the 0bit is about. Where do you see that?

There isn't another graph. With DVB cards, the transport stream is taken straight off the DVB card and written to the hard drive. The beauty of all digital.

Where are you setting the codec. In MP config? Make sure you're setting CoreAVC for h.264 only.

I notice you've got a 780G chipset board. Maybe take a look at your Catalyst drivers too. They can be problematic.

Maybe post a screen capture of your graph.

Now I can see one of the two channel with Cyberlink PowerDVD 8 H.264 decoder. Neither FFDshow nor CoreAVC works. The CoreAVC did not connect in the graph, FFDshow connects, but does not recognize the video. I think it is due to invalid video type, that is reported by the tsreader on the video pin.

When switching to the second channel, it mostly shows only first bricked image and nothing more, the bricked image is freezed. Sometimes is plays the video, but not very offen.

Hi,

HD channels work on my system only with the decoders delivered with my TV card: MainConcept
All other decoders I tried (CoreAVC, ffdshow) gave me similar results as yours: black picture with or without audio.

So its mainly seems to be a codec problem.

Is there a way to disable a Codec without deinstall it?

I have the same Problem and when i use Graph it looks like this
1. When i first look @ a normal TV channel and then join the HDTV channel, Graph shows @ video `"no Codec".
2. When i take a HDTV Channel and open Graph, i see that he takes my PowerDVD7 Codecs
BUT i don't choose this Codec in the MP-Configuration I wanted to use Divx HD Codec...

And yeah.. when i only use the PowerDVD Codec it aigain doesn't work.

I could Timeshift, Record the HDTV Channel and play it in PowerDVD Player but in MP and TVServer Preview there is well a blank screen.

So i think well it is a Codcec problem BUT you well say something about the Catalyst Config.
What should i Config in Catalyst?
My "normal Channel (Digital - not HD)" works when i disable some things in Catalyst but until yet i havn't found any setting to get work with HD.

Is there a way to disable a Codec without deinstall it?

Newest Catalyst Driver, HDMI Driver, Realtek Audio Driver..
Some ideas?
