I've seen this message before (every time I run ffmpeg) ...

... but no core dump - but then I haven't built the latest port.
Does it make a good recording ?

Most certainly it should not. I've just confirmed that the 0.48 port
does not reset the channel in this case.

There is much less cluttered source in bktrjpeg.c and in simple_grab.c,
I've deleted my copies but they were easy enough to find in the first place.
There is also bsdbktr_tvtune.c on ftp.sohara.org, which is probably very
similar to your C code and which I have just used to confirm retention of
tuning.
