For each capture card there is a tuner
chip that actually tunes to the correct channel, and an encoder that actually
encodes the content received into MPEG or V4l raw stream (this is a beginners interpretation
but more or less correct)
In this case you have a Oren Encoder (or
more likely Oren Compatible Encoder), and a Thompson Tuner that is combined
into an HD 3000 card.

Subject: [mythtv-users] FC4 and
HD-3000 DVB vs.QAM Issue in latest kernel
Hello All,
As soon as I start to trick myself into believing that I am actually starting
to get the hang of this (Been tinkering with Linux for about 3 months or so,
Myth about a month) something comes along and makes me think I couldn't pour
water out of a boot if there were instructions written on the bottom of it.
Anyway, here is my hardware (however I think it is a software issue):
AMD64 3200+ (Dual Core)
2 Gig Ram
MSI K8N Neo4 Mobo
Nvidia 6600 256Meg
HD-3000 (for OTA HD)
1 Terabyte of HD Space
I had this hardware up and running with Myth for the past week or two just
tinkering to learn/play and it was working pretty well. Because I did so
much "playing" with it, along with getting a DCT-6208 yesterday I
wanted to add (I know you don't have to wipe clean to add a source), plus I
just wanted more experience with Linux and Myth. I reinstalled FD4 this
afternoon from scratch.
I followed Jarod's guide the first time and it went pretty smooth. The HD-3000
was recognized and worked pretty much as close to "out of the box" as
you can get.
Now I am having an issue with FC4 and the latest kernel. I use the DVD ISO to
install FC4 x86 choosing the packages that Jarod lists. This installs
kernel 2.6.11-1.1369smp. When I finish the initial boot setup (enabling NTP and
setting up a user, etc) I log into X and look at the dmesg. (ie. NOTHING has
been done to configure/customize anything)

So it sees the pcHDTV HD3000 and creates /dev/dvb like it should.
then I run "yum upgrade kernel kernel-smp kernel-smp-dev"
It downloads and installs kernel 2.6.14-1.1637. I reboot into
that new SMP kernel and again look at dmesg after logging into X.

************************************************************
My question is, why does it detect the board as a "Oren OR51132
VSB/QAM Frontend"? It does still create /dev/dvb. The new kernel appears
to be using the 0.0.5 DVB drivers so I am going to guess that is what is
causing the difference in naming. Is there any issues with that? I plan to use
it for OTA HD only.
Also, what in the heck is a "Thomson DDT 7610 (ATSC/NTSC)"?
It lists that on both kernels. I am going to guess that it is something on the
HD-3000 card since there are no other cards/tuners in the box.
I just wanted to understand what was going on instead of continuing to
configure Myth and find out I need to do something now to save myself some
headaches down the road.
BTW, Happy Thanksgiving Everyone!
