Definitely correct.

Even better, what it currently does is /not/ create a thumbnail when the 
recording completes.  Instead, it creates a thumbnail--on demand--if
    a) there is no thumbnail
    b) there is a thumbnail, but the recording's lastmodified date changes.

The lastmodified date changes when a user sets a bookmark, when the 
commflagging process finishes, etc.

This approach is better because it works if the user is browsing the 
Watch Recordings list when the show is being recorded (i.e. started 
recording 5 minutes ago and you scroll across the show).  Also, it waits 
until it's ready to create the "final" version of the 
automatically-generated-after-recording-and-commflagging thumbnail to 
create one if a thumbnail is not requested before that point.
