What you concluded is what I concluded several weeks ago. :-)

If I wrote this, then I'm not too worried about it as it seems like more
of a feature rather then an issue.


I likely solved this problem of this user.

The kernel requires to be configured with CONFIG_VIDEO_V4L1_COMPAT (=y
or =m) enabled in order for Lirc to work properly (using the
Hauppauge_350 profile).  In other words, just screwing around now and
noticed the HVR-1950 remote stopped working after disabling this kernel
config.  Or, they could be still sol.  Brief clipping of my kernel
config follows:


#
# Multimedia core support
#
CONFIG_VIDEO_DEV=y
CONFIG_VIDEO_V4L2_COMMON=y
# CONFIG_VIDEO_ALLOW_V4L1 is not set
CONFIG_VIDEO_V4L1_COMPAT=y
CONFIG_DVB_CORE=y
CONFIG_VIDEO_MEDIA=y
