The 'frequencies' are the channel presets you enter on the remote to
change channel on the remote. They are passed to the changer script
when MythTV changes channel. Perhaps the SD information includes this
info for you. I know in the UK it still has to be entered manually for
any script controlled video sources.

Seems OK. Any chance the ivtv drivers are loading the cards
inconsistently (i.e. the /dev/videox device change)?

Ch+/Ch- only browses the channels available on the current video
source. Entering the channel number directly allows you to change to
the channel on another source if it is not available on the current
