DVB-T problem with ProgDVB Pro + AirStar 2

#1
Hi,

I have a problem with ProgDVB Pro and DVB-T card AirStar 2.
At the moment in my region (city Śrem in Poland) we have 2 DVB-T transponders (multiplexes).
One of them works great on ProgDVB but with the second I have 3-4 seconds delay of sound.

Codecs:
- H264: CyberLink PDVD10
- AC3: AC3Filer 1.63b
I have tried demultiplexers: Microsoft, CyberLink, Elecard and Prog.

I have tried 2 versions of ProgDVB Pro: 6.11.07 and 6.46.6. All have the same problem.

And the worst: I have tried other DVB application -DVBDream 1.4i (on the same codecs) and both DVB-T multiplexes work fine...

So, what is wrong with ProgDVB?
