I used to handle this with a file in /etc/X11/xorg.conf.d/90-mceusb.conf.
I suppose you could really just paste a section into /etc/X11/xorg.conf if
you wish.

Section "InputClass"
Identifier "Ignore MCE_USB as Keyboard input"
MatchProduct "Media Center Ed. eHome Infrared Remote Transceiver
(1784:0008)"
MatchIsKeyboard "true"
Option "Ignore" "true"
EndSection

Either I deleted that file or a Fedora upgrade nuked it.  I have it on my
backup.

You would just replace the MatchProduct string with "i2c IR (Hauppauge
WinTV PVR-350" and I think you can have anything you want for the
Identifier string.

Alternatively, set a udev rule as outlined in
https://www.mythtv.org/wiki/LIRC  -- Scroll down the page to "Double
presses for certain buttons"  Look at
http://www.gossamer-threads.com/lists/mythtv/users/504746#504746 for the
source of this article.

I was getting double presses for the arrows and I think the Enter/OK
buttons, and that fixed it.  I wrote that wiki section; I think it's still
valid.  I think what is happening is that the kernel is grabbing the input
at the same time as LIRC, so you want to block it if you are using LIRC.

Good luck!  You'll straighten it out.
