I too have the Verizon/Motorola HD QIP 7100 as well as QIP 2500-3 (both use the same remote). I initally tried the Motorola DCT2500 and it worked well, but there the DVR button didn't work and you couldn't stop DVR playback (these units playback video from the Home Media DVR).
I tried the Comcast DCT6412, but it didn't work at all. Then I tried the S1401_PL.bin in the QIP 6200 zip file (from this post viewtopic.php
f=17&t=1707#p6583). No go. So I tried the S1401_PK.bin. Boom!!! Blue Screen (I think it was IRQL_NOT_LESS_THAN_OR_EQUAL, but it went by too quick to get more than that). I wasn't sure whether to try the PL or PK because the post that it says to check out doesn't work (http://www.myhava.com/forum/viewtopic.php?f=2&t=1954
So now I've rebooted, reconnected and tried to go back to my DCT2500. Now if I try to click the Test button in the HAVA Setup Wizard, nothing works. If I exit the Setup Wizard and try the remote in the player, it works. Odd. I can live with the Test button not working, but it's painfully slow to go in and out of the player/wizard to try different remotes (is everyone's wizard this slow).
Can Monsoon/HAVA make the right remote driver for Verizon FiOS or can someone tell me which other remote really works the best.
