[mythtv-users] Sweet! PC HD3000 QAM_256 working, now about importing those channels?

[Brian McEntire]

Hi all,
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 
linuxtv.org <http://linuxtv.org>, make them, then scanned with:

./util/scan/dvbscan -vv -a0 -A2 
./util/scan/atsc/us-Cable-Standard-center-frequencies-QAM256 

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.

Filtered (known working) results, changed only the first field to end up 
with:

NBC:561000000:QAM_256:16:17:1
ABC:561000000:QAM_256:144:145:3
CBS:567000000:QAM_256:16:17:1
FOX:567000000:QAM_256:144:145:3


Now I can successfully tune to any of those channels like so:
azap -c ~/.azap/channels.conf -r NBC

status 1f | signal fdf2 | snr fd9f | ber 00000000 | unc 00000000 | 
FE_HAS_LOCK
status 1f | signal fdf2 | snr fd8d | ber 00000000 | unc 00000000 | 
FE_HAS_LOCK


And I can cat /dev/dvb/adapter0/dvr0 > /tmp/out

And play thay back (and it looks really nice) with:
mplayer -vo xv -fs -zoom -vf pp=lb -framedrop /tmp/out


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.

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.)

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.

Any ideas?
