 If you configure the wrong VBI device, or have another application reading
 VBI data the blocking read for CC data gets stuck waiting for data, so it
 is impossible to shutdown the recorder. I noticed this while working on
 #843 and trying to switch back to a NupperVideoRecorder that I had been
 using earlier.

 The CC decoder is also hard coded to the default VBI format for Bt787
 cards. It does not decode CC data on the cx88 cards in their default
 configuration, nor does it work with bt787 cards if the VBI format has
 been changed externally to MythTV.
