If you connect the PVR-250 via composite or S-video, it will no longer
try to tune. Note that you'll have to change the input settings in
mythtvsetup -- eg to svideo0 from tuner0.

You'll also get a better quality picture this way.

If you absolutely have to use coaxial, then find the part in
mythtvsetup that asks for the channel to tune to and the external
channel change script. Enter /usr/bin/true as the script to prevent
the PVR-250 from tuning to a different station.
