Comment 12 for bug 458444

 just an update for all and sundry.
I did a clean install of karmic and plugged in my leadtek gold usb tuner purchased ~3 weeks ago
It loads 4.65 firmware and works out of the box but has the polling issue with the remote.
I then removed and plugged into a windows pc and installed the 4.95 firmware on my karmic install.
I plugged it into karmic and it loaded the 4.95 firmware.
It would lock on channels but would take up to 2 minutes to lock.
The polling issue was not present.
So If you want a cheap tuner in Aus these are great for a mythtv backend where the remote isnt required.
All you need do is this:
echo "options dvb-usb-af9015 remote=-1" > /etc/modprobe.d/no-af9015-remote.conf
which will disable the polling and you have a cheap dvb tuner that works great.
