No video showing during trasmission

I have installed Tutione with a PCI card TT S2-3200 on a PC with windows 7 using a NVIDIA RIVA TNT2 Model 64.
I use a DIGILITE Transmitter with SR=4000 and FEC=3/4. All the lights on the screen (Carrier, Synchro, etc.) are green but no video is showing on the central portion of the screen. However if I record a .TS file I am able to reproduce it correctly using VLC.
I installed the codec clvsd.ax from powerDVD as well ffdshow as explained in this post viewtopic.php?f=28&t=109. Video card nvidia drivers are correctly installed and working.
What could be the problem? Any suggestion?
Thanks.
