I'm always glad Mike is on here.  He knows the stuff.

Could you possibly have created a few "record this episode" rules and 
set them to ignore previous?  A quick scan through the Recording Rules 
will show any spurious rules for that show.  Do you have other rules 
based on Actors or other keywords that are coincidentally finding these 
episodes?  Aside from something like that, I'm thinking these few 
episodes are coincidentally "generic", as Mike suggests.
