The KWorld UB435-Q V1-3 tuners work fine in TotalMedia, Hypermedia Center and TiVme on Windows; also in Kaffeine and MythTV on Linux.
These tuners work fine with ATSC (North America) over-the-air channels (8VSB) in MediaPortal, Next PVR and Windows Media Center.
They do NOT work with "clear QAM" cable tv channels (QAM256) in these programs.
THE PROBLEM:
-----------------
Quoting NRivera637, "This tuner presents itself as an ATSC/QAM tuner. Each tuner thinks it's an ATSC/QAM tuner, runs as an ATSC tuner
but searches for DVB-C frequencies. There is no DVB-C in North America therefore nothing will ever be found."
THE SOLUTION:
------------------
Create a DVB-C file containing ATSC frequencies!
This fix should work with V1, V2 and possibly V3 tuners.
I copied the freqencies from the C:\ProgramData\Team MediaPortal\MediaPortal TV Server\TuningParameters\atsc\QAM Standard.xml
file into one of the C:\Users\Public\NPVR\Tuning\DBC-C files (using it as a pattern and removing the extra entries of course).
Next PVR scans my channels just fine!!!
I have Frontier (formerly Verizon FiOS) in the Tampa Bay area.
NOTE: If I understand this correctly, this should work for any cable company in the USA because they all use these QAM256 frequencies.
I used the ATSC frequencies from "QAM Standard". If you have "QAM Std Alternative", "QAM HRC", "QAM HRC+3" or "QAM IRC" channels you will have to make a separate file for the one you need using these same frequencies.
1. Install Next PVR.
1a. Make a directory named C:\Temp (Stops the "Live TV Buffer" directory missing error.)
2. Copy the "United States - All ATSC Frequencies.ini" file into
C:\Users\Public\NPVR\Tuning\DVB-C
3. Right-click the "NPVR" taskbar icon, choose "Show Settings".
(If its not there, click the "NPVR"/"Start NPVR Service" shortcut first.)
In the "Devices" section, click the "DVB-C Tuner for Windows Media Center"
(NOT the "ATSC/QAM BDA 2870 TVTuner"), then after "Priority" click "Up" until this tuner is at the top.
Click "Device Setup". After "Country"/"Region" select "United States" and "All ATSC Frequencies".
Click the "Scan" button....
The idea for this solution came from "mm1352000" in these threads:
