Another possibility: if you're *editing* the existing capture cards, won't  
mythtv-setup already have opened the tuner ? So it won't be able to open  
it again via your new symlink = 'failed to open'

Whenever I do this sort of thing I always 'delete all' capture cards  
first, then define new ones...
