I ended up installing a Windows98 on small partition and tried the card
under that OS. The TV app coming with the card didn't show any image on
screen, however it did find all the channels within my area during a
scan and it also recorded a couple minutes of video without a glitch.

Shall I try to replace the card for a different kind? Maybe an AverMedia
DVB-t?

Or do you have any idea of what might be going wrong here?
