If it's just different types of sausage, then you can use the Deny string (at the bottom of the filters, as the last one matching is the one that's applied):
sausages*dvdr* | D
and/or be more specific in your Accept strings:
*teevee*sausages*S04E*720p* | A
*teevee*sausages*4x*720p* | A
If it's duplicate sausages, or even spam virus-infected sausages you're trying to avoid (yuck!), then that's a bit more complicated. I really recommend looking at those other sites, their feeds are much more user-friendly for sausage lovers.
