ProgDVB Pro: cannot decode DVB-S2 channels

#1
Hi, after registering ProgDVB I wanted to see DVB-S2 channels, the free version correctly showed that this is a S2-channel and cannot be decoded, so the detection is working.
I am running Vista32bit and latest ProgDVB4 Pro.
I have installed CoreAVC and Cyberlink PowerDVD's included H264 decoder. Both work for recorded movie files or in other applications like TT Mediacenter or AltDVB. I also downloaded and installed the Elecard H264 decoder trial.
But whenever I switch to a DVB-S2 channel (German Sat1 HD or Pro7HD for example), after tuning finished and status is green, the display remains black. The filter list doesn't show any used filters at all. This happens whatever graph I activate in the video options. And there is not even a filter error when selecting a filter, that doosn't exist on my maschine.
I then booted my rather fresh installed XP and tried to run DVB-S2 channels there, the same effect here.
The only other directshow filters I have installed on both machines are haali mediasplitter, which I use to open all kinds of mpeg2-ts and h264-ts from harddisk.
Is there a solution for this problem? As this was the mayor cause for regging progdvb.
Thanks.

I did some more research today, I created quite alot of different filter graph files using all my installed h264 decoders based on the included avc files. I edited directly the XML so that the source, the splitter and the outputs are the same.
But I still can not get progdvb to decode any hd s2 channel.
As i also don't get any error message when trying to add a filter that doesn't even exist on my system I think the problem lies before that.
There may be a problem with the progdvb splitter that does not accept the input data.
Even the custom graph created in progdvb5 doesn't give me any result.
I also uninstalled haali media splitter and some other directshow splitter components, but still no go.

As ProgDVB cannot get the audio and videostreams it cannot record or view the channel. When recording nothing is recorded.
The filter list is completely empty.
