- WinTVCap
Had a request for a few things:

• Support multi-board installations
  
• Be able to override recording quality settings per programme
  
• Do not insist on stopping WinTVCap if already running

The last one is now the default operation for DABDig because modern versions of WinTVCap can handle being run twice (for same board) - by closing first recording and starting the new one.
All done (251b12 and 251b13)
