Comment (by pholmes at india.com):

 Sorry for not getting back with a patch. My system is at home so it takes
 a at least a day to respond normally.

 The current change of scheduling a redraw will not work correctly in the
 case of VBI_IVTV. This is due to the function
 OSDTypeTeletext::AddPageHeader that shall call PageUpdated that will
 schedule the redraw will also erase the current page data
 (memset(ttpage->data[0]+40, ' ', sizeof(ttpage->data)-40); - as a side
 point this should always be done for any VBI type. If not, and the VBI
 does not always supply all rows of text you will get old subtitles left on
 the screen)
 The fix should be just to copy the current page data to a draw page that
 the draw function us.
