[mythtv-users] femon only works with mythbackend stopped?

I'm running Gentoo with media-tv/linuxtv-dvb-apps-,
media-tv/mythtv-0.20.2_p14324 and kernel 2.6.22-gentoo-r9.  I have
three HD-5500 cards used only for ATSC OTA broadcasts.

Everything I keep reading indicates that I should be able to monitor
signal strength with femon while the backend is running, which would
be awesome...I've been looking for a way to do that.  However it only
works with the backend stopped.  If I try to use it while the backend
is running the only output I get is:

opening frontend failed: No such file or directory

...on all three of my adapters, even though the device files are there.

Is this supposed to work?  If so, any ideas why it wouldn't?  Thanks.
