Is your problem.
This means it can't write to the decoder device you have specified in the
350 configuration.
This is done in the setup .... section where you ticked the box to enable
350 output. 
Make sure that it says use 

/dev/video16
And that /dev/video16 exists and is a device not a file and is writeable by
the user running mythfrontend.
