 Hello there,

 I have observed that whilst watching a DVB (not ATSC) recorded program
 with DVB closed captions switched on, that captions may remain on screen
 indefinitely.

 Allow me to clarify using example:

  - The last line of dialogue prior to a commercial break may be 'Goodbye
 sir'.  The caption 'Goodbye sir' appears as it should - however, this
 caption may remain onscreen for the duration of the commercial break -
 until it is 'cleared' by a new caption.

  - There may be significant period of silence between one dialogue and
 another. For this duration a caption will remain on screen, only to be
 cleared when the new dialogue is captioned.

 If I tune DVB using my Television receiver, captions behave 'normally' -
 as they used to in previous versions of MythTV.  I have only observed this
 since upgrading to .24 (from .23) - which was some time ago now.

 Also, though I realise this is not the forum for feature request but I
 also notice that Closed Captions (DVB) appear consistently somewhat
 prematurely.  That is to say perhaps 300 milliseconds (or more) before
 they normally would (if watching DVB using TV).  Could there be a funtion
 added to 'delay' captions before displaying on screen?

 I trust my report makes sense - let me know if otherwise.
