Yes, things look normal.

The messages in dmesg are normal for now.
It looks like you have a signal strength problem, a signal to noise
problem, you don't have any digital stations available, you may not have
used the right options to the scan command, or you may not have waited
for the command to finish.
It is normal to get tuning failed results for most frequencies, but you
will get a message for stations you detect.
On Fedora 7 with I used the following command knowing that I was only
looking for over the air ATSC broadcast:
$ $ scandvb -A 1 -a 0 /usr/share/dvb-apps/atsc/us-ATSC-center-frequencies-8VSB
scanning /usr/share/dvb-apps/atsc/us-ATSC-center-frequencies-8VSB

Done.
The services list can then be put in a channels.conf file for mplayer or
azap.
If you didn't get any services, check
a. that you have the cable connected to the ATSC input of the card
b. that you have the right arguments for the "scan" command
c. that your antenna is pointed towards the stations you want,
http://www.antennaweb.org can help in the US
d. ways to improve you signal strength given:
http://www.ivtvdriver.org/index.php/Howto:Improve_signal_quality
e. get a high gain UHF antenna for ATSC signals. It is currently rare
for VHF frequencies to be used for ATSC, but that may change when the
analog NTSC signals in VHF must be turned off.
I hope this helps.

Andy
