Windows MCE Compliant, Vista Certificated tv-tuner.
This card does not have possibility to transfer audio stream via PCI,
only by direct connection via external audiocable from tv-tuner to soundcard line-in.
In WMC work OK.

If I try to scan channels MP says me:
"Unable to scan. Mostly your card is not supported by TvServer."
Tried to install InterVideo WinDVR, no success.

Logs attached.
