If I'm not mistaken the PVR 150 is an analog card and will not be able to
see digital transmissions picked up by your antenna.
Where you see this "/dev/dvb/adapter0/frontend0" on the same page should
appear some card specific info, indicating that the card is opened, then it
is a matter of choosing the correct tuning parameters, I believe on the
next page, and you should find the same channels that your TV finds
