I have info for an AverMedia, AVerTV HD A180 (AVerTV HD MCE A180), more info on this card at MythTV's website
http://www.mythtv.org/wiki/AVerTV_HD_A180Two informational quotes from MythTV's website
AVerTV HD A180 is an HDTV tuner for OTA (ATSC) or unencrypted digital cable (QAM) signals
and
The card uses an nxt2004 Frontend chipset with an saa7135 bridge interface. This is similar to the ATI HDTV Wonder and the Kworld ATSC 110.

I think this is a great card with a great picture, I have had it in operation for a little over 2 years now. First year in just a stand alone myth system and last year in a LinuxMCE 710 system and now I just recently upgraded to 810 and it manually installs fine. I have compared the picture side by side with Myth's "PBP" (picture by pictue) feature against a HDHomeRun both in full 1080p and in my opinion it has just as good of a picture and I can't tell the two apart. My comparison test has only been for OTA HD (ATSC 8VSB).
The only thing I had to do was download the firmware and copy it into the /lib/firmware directory and rebooted and it worked.
One final note, the script to download the firmware is broke but here is a note from
http://www.mythtv.org/wiki/Kworld_ATSC_110 and also
http://www.mythtv.org/wiki/ATI_HDTV_WonderNOTE: Running the perl download script causes wget to exit with a 404 error. This is caused because aver.com updated their domain to "www.avermedia-usa.com". To fix this you must edit 'get_dvb_firmware' at line 320 after the gzip -d command. Replace 'www.aver.com' with 'avermedia-usa.com' and it should download properly
Both the Kworld and ATI Myth sites are very helpful because the A180 site seems to be a little outdated.
If there is any other info you need just let me know.
Good luck, TinkerMan
