That only works for webcams tho, having a /dev/input/event* node
too suggests it is an anlog tuner (where the /dev/input node would
be for a remote which could be used with comms/lirc), and in that
case the OP needs to try something like mplayer (built with the V4L
knob enabled), or vlc (?, all in ports under multimedia/), or tvtime,
tho I think the latter isn't in ports yet. (since most people these
days use digital tuners I guess, which would appear as /dev/dvb/adapter*/*
and can be tested with w_scan, mplayer, vlc, or even mythtv or vdr.)
Actually I'm not sure, maybe mythtv can be used with analog tuners
too...

 Oh and now I see the OP also posted in -hardware, where he shows
webcamd logs that say its an em28xx device, to the OP:  If you
get that working I'd like to add it to the wiki here:

	http://wiki.freebsd.org/WebcamCompat

so I'd like to know the Name, usbids and other details for it.  And
I think there are dual analog/digital em28xx tuners also so be sure
to check if you get shomething in /dev/dvb for it too.

 Good luck! :)
