I don't use Plex but have a similar card and Motion does not interfere
with it.?? Motion can not process /dev/dvb devices and only processes
/dev/video devices so I would suspect that it has to do with how Plex is
starting.? If Plex is set up to scan for /dev/video devices, then it is
possible that is trying to grab your /dev/video device and when it is
already being used by Motion, it terminates and does not continue to
look any further for the /dev/dvb devices.
I'd suggest seeing if Plex can stop looking for the /dev/video device,
possibly using udev rules to create a symbolic link to the device, or
maybe setting up a v4l2 loopback device on the camera.
The last choice of course is to revise the startup rules to put a
dependency upon Motion to only start after Plex has finished starting.?
(Others may be able to provide guidance on how to do this)

I modified the following line in /etc/init.d/motion:
# Required-Start: $local_fs $syslog $remote_fs plexmediaserver
Added plexmediaserver and startup now works without any problems.
