On second thought, it's less rare than I implied.

Interestingly enough, though, it seems that commercials often look
different in their use of CC.  E.g., I dump CC info to a file, and
commercials often look double-spaced in their CC data whereas normal
shows are single-spaced, or are often in all-caps whereas the show may
use mixed-case, etc.  However, it's too random to depend on; perhaps it
might be predictable (or learnable) for certain channels, but it seems
unlikely there'd be one setting that worked for most people.
