One other remark:

be very carefull with "scanning" the network. It will fail and destroy 
the dtv_multiplex tables as @home (as many cable operators) is using a 
different interpretation of the DVB standard with respect to NIT-Actual 
and NIT-Other.

MythTv uses NIT-Actual to determine frequencies, and @Home is using 
several NIT-Other where you need to know which one to use.
