I have been using this card on FreeBSD as well as its `cousin'
TT S2-3600 which uses the same driver with various versions of
webcamd which used various versions of the Linux v4l/dvb tree
(media_tree), first with bits from s2-liplianin merged in and since
(I think) 3.2 using the pctv452e.c driver that was committed to the
vanilla media_tree, and rarely ever had issues.  Currently I'm using
webcamd which uses a snapshot of the for_3.5 branch of

 I have been testing various other usb tuners (mainly dvb-t) on FreeBSD
with webcamd (which as mentioned above uses linux' media_tree), see
my (nox) entries on this page on the FreeBSD wiki:

 Besides the pctv452e/TT S2-3600 dvb-s2 tuners which _I_ had not
many issues with I successfully tested the following dvb-t tuners
using dib0700 hardware:

        PCTV NanoStick 73e SE (solo)    [single tuner]
        Hauppauge Nova-TD model 1172    [dual tuner]

 The Sony PlayTV which was mentioned later in this thread seems to
use dib0700 hardware too, but at least here it seems to be much more
expensive than the Nova-TD.

 (And the two af9015 tuners I tested didn't overheat but used to
hang themselves up needing a temporary unplug when left running on
vdr for a day or less, this _seems_ to be better with recent media_tree
versions but I still had to restart at least vdr when it happened.
You can reduce the probability for this to happen with vdr tho:
change the osd setting "Setup -> DVB -> Update channels" to "names
and PIDs" or lower.)
