Furthermore, because "Never Record" only simulates recording of a 
specific episode, it will only prevent recording if duplicate matching 
is enabled on the recording rule.  And because it relies on duplicate 
matching, it has the same requirements/limitations as all duplicate 
matching....  If there's a program ID, it (that existed at the time the 
"Never Record" was submitted) will be used to determine whether a 
showing is the one to "Never Record".  If the program ID is a generic 
episode ID, the "Never Record" will do absolutely nothing (instead 
requiring a filter on the recording rule to exclude/ignore generic 
episodes).  If the showing that is marked to "Never Record" has no 
program ID, the specified duplicate matching algorithm for the recording 
rule for the show will be used (i.e. subtitle and description), and if 
any of that information changes, due to program listings updates (i.e. 
determination of which teams are playing or whatever), the episode will 
no longer be considered a duplicate.

As for the "Don't Record", that creates a specific one-time override 
rule.  And, again, it can be "fooled"/broken by listings changes (even 
if it's only the start and/or end time that's changing).
