Please try adding the following line in the cDvbApi::SetChannel() function:

  if (this == PrimaryDvbApi && Ca && Ca != Index() + 1) {
     cDvbApi *CaDvbApi = GetDvbApi(Ca, 0);
     if (CaDvbApi) {
        if (!CaDvbApi->Recording()) {
           if (CaDvbApi->SetChannel(ChannelNumber, FrequencyMHz, Polarization, Diseqc, Srate, Vpid, Apid1, Apid2, Dpid1, Dpid2, Tpid, Ca, Pnr)) {
+             usleep(500000); // avoids distortions (apparently switching into replay mode immediately after tuning causes problems)
              SetModeReplay();
              transferringFromDvbApi = CaDvbApi->StartTransfer(fd_video);
              }
           }
        }
     }
