I fell back a little put on this unknown map internet forums ... Well took me.
I pass the software, as I do not use (I use MediaPortal 1.2.3).
The card works fine, the images are better than with Terratec zapping channels is faster (from 3 seconds to 1 second for Terratec TBS). The dual-tuner responds perfectly, and no concern for tuning TNT channels.
In addition, this card has several additional inputs for other video sources (which I have not tested) while the Terratec is exclusively reserved for the TV signal.
In short, just happiness. 20% more expensive than the Terratec but 100% better.
