Hi all,
On Saturday we had some difficulty
getting the Avermedia PCI DVB-T card working 
with Mythbuntu 10.04.
I took it home and built a Mythbuntu
10.04 system and put this card in, I also 
had the same problem i.e. i could not
scan for channels.
Looking in the messages log (tail -f
/var/log/messages) I could see that the 
system could not find or load the
firmware for this card.
After some research I found that we
were not the only people who have 
difficulties with this card, but there
is a solution. Apparently the system 
incorrectly identifies the card at
startup and tries to load the wrong firmware 
which fails and makes the card
unusable,
The solution to this is to update the
kernel within 10.04 this is done by just 
asking the package manager to update
the kernel and then rebooting.
Once this is done the system will
correctly identify the card.
Next we have to download and install
the firmware for this card, this can be 
done by installing the Ubuntu firmware
package using the package manager the 
package is named
linux-firmware-nonfree.
This appears to work and allows you to
configure MythTV and scan for channels, 
when I performed the scan at home I
found 41 TV channels and the 5 I tested 
all were watchable even though the BBC
channels were picked up from the 
transmitter in Wales instead of Winter
hill.
After rebooting the computer I found
another problem when using this card with 
Mythbuntu, the myhthbackend process is
configured to startup before the system 
has finished configuring the hardware.
The loading of the firmware takes time
and the card is not ready until this is 
finished.
The solution to this is:
Modify /etc/init/mythtv-backend.conf as
follows:
 
 Replace line
 
 start on (local-filesystems and
net-device-up IFACE=lo)
 
 with
 
 start on (local-filesystems and
net-device-up IFACE=lo and started udev-finish)
This makes the startup process a bit
longer but it does make sure the hardware 
is ready.
Donald.
