Ping!! First, did this hep Theirry?
And I am still dead here,
I have installed all the xawtv stuff only to find that no ATSC
functionaliy has been added. It can get the 1 signal from a 10 watt
translator about 20 miles away that is still broadcasting in NTSC
format, but at that distance and wattage, the signal to noise is about
1/1 when conditions are good, perhaps 5% of the time.
I have installed all the dvb_apps and friends, but while it finds
the "Oren OR51132 VSB/QAM Frontend" doesnt support TERRCABLE_ATSC
apparently not finding the atsc list for std terrestrial broadcasting in
the US, so until I can find a configurator to tell it different, thats
out.
That leaves kaffeine, whose scanner scans about 3 or 4 channels a second,
not giving this card adequate time to lock to the signal so it
registers.
the KDE version of kaffeine did in fact work well with this card an
iteration or 2 back up the log, not too long before I installed TDE in
fact. However, I can find no means to slow its at least 10x too fast
channel scan that it does now. And the site it got program listngs from
seems to be defunct too.
Is there not another application yet that will play ATSC broadcasts?

kaffeine can display HD TV, but I've had to move some firmware around
so it could be found and uploaded to my card, and I can report that tv
test utilities that are supplied by the pcHDTV-3000 card (that I have)
vendor, now display all the local channels signal strengths with
dtvscan, and that dtvsnr now reports sensible values on the active
channels, and likewise dtvsignal shows sensible signal strengths on
the locally active channels.
HOWEVER, kaffeine is not finding what dtvscan discovers, IMNSHO
because it scans about 20x faster than the card can achieve lock on a
new frequency, ignoring the 1.5 to 2 or even 5 seconds allowed for
lock time in one of its setup menu's. kaffeine's scanner claims it
has scanned half a gigahertz and found nothing in something under a
minute. dtvscan takes around 3, maybe 4 minutes, starting at channel
2, to find and report good signals on north american atsc channels 5,
10, 12, and 33.
In the event that it works for HD with winderz
but not linux, the
list to ask next would be the v4l list on vger.kernel.org (I
think, I've not been on it in a couple years) Some pretty sharp
digital video folks hang out there. You'll need to show them the
lspci or lsusb/lshw output so they can properly ID the chipset in
the stick.

I can confirm that it works with Windows (same stick, on the same
machine). There seem to be two problems:
a) Can Kaffeine display HD TV? If not there's not much to do short
of looking for another program. b) How can I create a new program list, as w_scan
crashes (so badly
that it locks the machine competely).
You may have something missplaced, before I could make the cards
software/firmware load, I had to cp the contents
of /usr/lib/hotplug/firmware/* to /lib/firmware. It seems todays
systems have moved the default location for this stuff, which for my
card, was set 9 years ago, in 2007. Along that same train of thought,
perhaps something kaffeine needs has been moved. Its all stable here,
no crashes while exploring the dvb menu's, but it doesn't work either.
I see it has the ability to manually add a channel but haven't tried
that, I should have at least one eye open, which this time of the
night locally, isn't always the state. Theoretically, I should be
able to use the data that dtvsignal reports to compose a manually
added entry.
These utilities I mention are of course specific to this card,
hopefully you have similar utilities available for your card or
dongle?
So you may want to take a look at your dmesg output for messages
similar to this:
[56092.124304] or51132: Waiting for firmware

Which should look more like this, card diffs notwithstanding:

And, noting the cx88 above, an "lsmod | grep cx88" returns quite a
lengthy list of suspects:

I would assume that for whatever chipset is in your device, you would
be getting a similar output as above, chipset diffs notwithsranding.
Maybe there is a clue here for you. For me, its plain that kaffeine
itself isn't functional as currently configured on my machine, using
the TDE version of 8.8.
I'll take a look at the v4l list. thanks.
