I've found you need to give the channel scanner some "starting" values - 
It then seems to find all other options by itself.

The values you need can be found in a channels.conf file, as used by the 
tool "tzap". Such a file can be created using the tool "scan". Example 
.conf files (as well as the tzap and scan apps) are in the Debian 
package dvb-utils.

For example, from 
/usr/share/doc/dvb-utils/examples/channels.conf-dvbt-oxford.gz (Oxford 
area transmitter):

BBC-Choice:578000000:INVERSION_OFF:BANDWIDTH_8_MHZ:FEC_2_3:FEC_NONE:QAM_64:TRANSMISSION_MODE_2K:GUARD_INTERVAL_1_32:HIERARCHY_NONE:620:621

The values are handily in the order Myth wants them, so just plug in 
numbers until you run out of spaces, and hit next - it'll then scan not 
only that frequency, but all others which are "linked" to that one, e.g. 
in my case 850000000 and others are also scanned when i ask for 578000000

This may or may not be the intended behaviour, but it works for me.
