Success! We managed to get the Direct TV remote to control our Viore PDP42V18HA by setting up the remote to control the TV under the AV1 input (instead of the TV input) and using the code search. When doing the code search and the TV responds, make sure you hit the Select button immediately (or you might as well start the process over). Also, cover all the other A/V components' sensors (we used a towel) so that they cannot interfere. Unfortunately, we cannot verify the code selected per the procedure outlined in the Direct TV manual (p.11 at [Link: directv.com]) because the green light does not blink, so I can't post what the final code was, but the Direct TV remote is now controlling our Viore TV for every function.
