No, what Robert meant to say, in plain English,
is that pretty much ALL "DVB" cards can record multiple
subchannels of a single physical channel simultaneously.

So, if your local PBS station, for example, is on 17.1, 17.2, and 17.3,
then those three "channels" are actually "subchannels" of a single
physical channel.  And the HVR-1600, like just about all other tuners,
can record any combination of one, two, or all three of those simultaneously.
