I've given this a try and it's not gone how I thought it would. I did
the "Delete All" things and then went into channel editor to do a
scan. I tried to get the channel data in 2 ways:

1) Import channels.conf by specifying the location of the
channels.conf file as /tmp/ (this is where I'd put it from a previous
run of "scan" at the linux command line. The screen then went blank
and didn't respond for a good 10 minutes, at which point I did a
Ctrl-Alt-Backspace to restart X.
I also tried specifying the file as /tmp/channels.conf but that didn't
create any channels.

2) Do a full scan.This told me that it found x non-duplicate channels
and y duplicates. I found this horribly confusing because if I
selected the option to insert the duplicates it wanted me to give them
all unfriendly numeric names. And if I chose not to insert them I
ended up with channels missing (in which case perhaps they weren't
duplicates after all!) How come it finds duplicates? This never used
to happen to me on previous versions of MythTV when I did channel
scans.

So I now seem to be stuck, unable to populate the channel data.
Unfortunately the Frontend Channel Editor pageon the wiki didn't shed
much light on things either. It simply advises "Perform the proper
channel scan in mythtv-setup (8-VSB for OTA ATSC or QAM-256 or QAM-64,
with the frequency list that matches your cable system i.e. Cable,
Cable HRC, or Cable IRC)". I don't know what that means!
