I apologize in advance if asking you about the KWORLD ATSC 110 is inapproriate, however I see you name everywhere in discussion threads as you appear to be the developer. Looking through the threads, you also mention that you have ATSC working!
I am not the developer for this particular device, but I am the UNofficial linux-atsc maintainer, and I've been helping the developers with this over email. I HAVE written code to support AVerTV HD a180, which is similar in design, but not exactly the same.
The threads have been VERY helpful, but I've been trying for DAYS trying to get this working. The NTSC stuff works, SVideo and Comp work. I just can't seem to get the ATSC tuner working.
I wrote a quick howto @ http://linuxtv.org/~mkrufky/atscscan
I've downloaded the latest Mercurial tree (as of yesterday) and managed to get all of the drivers loaded.
Good -- You'll need this, since the driver will not go into the kernel until 2.6.17, the earliest.
I'm running 2.6.15.4 <http://2.6.15.4> Kernel, Knoppmyth.... Every time I try to do an atscscan /usr/local/share/dvb/scan/atsc/us-NTSC-center-frequencies-8VSB, all I get is:
---snip
>>> tune to: 701000000:8VSB (tuning failed)
WARNING: >>> tuning failed!!!
>>> tune to: 707000000:8VSB
WARNING: filter timeout pid 0x0000
WARNING: filter timeout pid 0x1ffb
[snip]

Try another scan file... The "NTSC CENTER FREQUENCIES" file works for me, but the "ATSC CENTER FREQUENCIES" file does not ..... other users have reported the exact opposite -- it depends on your area. I am in Brooklyn, New York. Where are you located?
Does the tuning failed message mean that the tuner modules didn't work, or that there was simply no signal on that channel?
no signal
Here is part of my dmesg showing the v4l and dvb modules, is this the way it's supposed to look? Linux video capture interface: v1.00

Yup... Looks good, although I see that the tda9887 does not report anything... just as Curt says. Maybe we need some special handling for it...... Any ideas, Hartmut, Hermann?
Again, I apologize for bugging on this, I'm not sure how to post messages lists that I saw you threads on.
Yes, generally I dislike private emails like this, but I understand your situation... For information on how to subscribe to both video4linux and linux-dvb lists (cc's added) , please go to:

http://linuxtv.org/lists

... there you will find links to:

http://linuxtv.org/cgi-bin/mailman/listinfo  -- linux-dvb
https://www.redhat.com/mailman/listinfo/video4linux-list  -- video4linux

Please subscribe to these lists before you reply to this email. I have added cc's to the lists, but the linux-dvb list is subscriber-only, and will require your registration before you can post to it. ...and remember to use REPLY-TO-ALL when replying.

I hope this helps,

Michael Krufky
