As I understand it, it should just be handled like any other set of
mplexes, with no special handling.

The mplex which is supposed to carry the EIT data is the one which
would actually need special handling.

There are signalling tables which indictate when it is appropriate
to use a specific mplex to collect EIT data. The non freesat channels
on the same satellite are an example of this.
