Hi all,<br>
I'd heard rumors that PC HD3000 cards could receive clear QAM. I
can confirm. Mine is working well. I had to grab the latest dvb-apps
from <a href="http://linuxtv.org">linuxtv.org</a>, make them, then scanned with:<br>
<br>
./util/scan/dvbscan -vv -a0 -A2 ./util/scan/atsc/us-Cable-Standard-center-frequencies-QAM256 <br>
<br>
After a few minutes, this dumped all the channels found to stdout. It
found many more but most are probably the encrypted QAM variety. After
testing them by tuning with azap and then cat'ing and mplaying the
(below), I found the four I expected to be clear QAM and threw out the
rest.<br>
<br>
Filtered (known working) results, changed only the first field to end up with:<br>
<br>
NBC:561000000:QAM_256:16:17:1<br>
ABC:561000000:QAM_256:144:145:3<br>
CBS:567000000:QAM_256:16:17:1<br>
FOX:567000000:QAM_256:144:145:3<br>
<br>
<br>
Now I can successfully tune to any of those channels like so:<br>
azap -c ~/.azap/channels.conf -r NBC<br>
<br>
status 1f | signal fdf2 | snr fd9f | ber 00000000 | unc 00000000 | FE_HAS_LOCK<br>
status 1f | signal fdf2 | snr fd8d | ber 00000000 | unc 00000000 | FE_HAS_LOCK<br>
<br>
<br>
And I can cat /dev/dvb/adapter0/dvr0 > /tmp/out<br>
<br>
And play thay back (and it looks really nice) with:<br>
mplayer -vo xv -fs -zoom -vf pp=lb -framedrop /tmp/out<br>
<br>
<br>
I hope this might help someone with the same card or other DVB cards.
I've gotten this far from a couple of excellent posts seen here
recently.<br>
<br>
Now the question... Has anyone figured out how to import these
channels into MythTV? I'm running 0.18.1. Inside of mythtv-setup, the
only channel scan setup options seem to be ATSC or Cable. I tried cable
but it doesn't find these channels even though the newer versions of
dvb-apps find channels while scanning. (Not too suprising.)<br>
<br>
I see there is a manual way to add channels, and since I only have 4,
that would be fine, but is there a way to find out the zap2it XMLTV ID?
I'm signed up with zap2it, and I selected a program line-up and
unchecked all but those for channels in the 700 range which are clear
QAM. But now I'm a but stuck as to how to proceed. I previously
downloaded zap2it listings when I was using OTA ATSC but not that I'm
trying to get QAM working, I'm not sure how to get these channels set
up in MythTV.<br>
<br>
Any ideas?<br>
