Wrong.  

/dev/video is used in the current driver to provide the V4L functions - 
overlay, still-frame capture etc.  VDR doesn't use these functions directly, 
but makes them available via SVDRP, so it opens the device on startup.

A better solution would be for VDR to open it when needed and close it 
afterwards - but I'm sure Klaus will get to that once he has completed the 
more important work.

Dave.
