No, I mean audio subchannels. In some cases this means separate language 
tracks, but with our cable company that means that channel 87 has 
something like ten radio stations under it -- on her TV display we see 
them as 87-00 through 87-09 with a blank screen. We also notice that her 
TV seems able to pop a box with information about the current network 
and show, something I presume Myth's onscreen box gets from its listings 
rather than the cable signal itself (but I could be mistaken here).
