<br> You can use the DVB utils to check the errors you are getting. You'll<br> need to scan for channels using the scan tool. You'll probably also<br> need to stop mythbackend to free up the device. I did it like this<br>
on debian using QAM:<br> scan -A 2 -U /usr/share/doc/dvb-utils/examples/scan/atsc/us-Cable-Standard-center-frequencies-QAM256<br> <br> You'll need to save the channels it found to ~/.azap/channels.conf.<br> <br> Then you can run 'azap channel' (hopefully you got meaningful channel<br>
names from the scan), which will just tune the channel and<br> output some statistics. The 'ber' output from that is the most useful.<br> It means bit error rate. It should be practically zero. You probably<br>
want to check several channels.<br> <br> There is some more information about the DVB utils here:<br> <a href="http://www.linuxtv.org/wiki/index.php/Zap">http://www.linuxtv.org/wiki/index.php/Zap</a><br> <br><br> </blockquote>
</div>Thanks for that. I had tried the "scan" tool previously, but with no success - I had failed to stop mythbackend first.<br>

See, now you all have saved me the pain of buying a new CPU/Mobo, only to see the same problems as before :)<br>
