Just as an idea... Are you sure your antenna has the appropiate amplifiers
for that frequency? I had a similar experience (the Nova-T 500 locking only
on a reduced number of channels and a standalone receiver on all of them),
and the problem solved when the building administrators added the amplifiers
for all the frequencies that missed.

It turns that the signal amplifier in most standalone players is waaaay more
powerful than the Nova-T one, so they are able to lock on the minimal signal
capted directly by the antenna, but this is not the case for the card.
