I have exactly the same card and am experiencing similar issues to you.

I definitely have the inbuilt amplifier turned on. I have also
replaced my antenna and all antenna wiring in the house to try and
reduce the bit error rate. I have a signal strength of 80% and above
across all channels and noise at 0% so I would expect not to see the
pixelation etc. I can see the antennas in the hills and there are no
trees or anything between to spoil the signal. The last thing for me
to change is the tuner card to see if another brand might provide
better results.

Can anyone recommend a better Australian version DVB-T tuner card? It
needs to be low profile (small form factor). I have spare PCI and PCI
express slots available.
