A scan a few minutes ago now shows the old settings, 79*, as disabled
(0) and the new values as ITV4/24/1734, ITV3+1/34/1735 and 
CITV/122/1736.  It will probably work like that... but perhaps those 
chanids will eventually revert to their usual relationship with channel 
numbers?
Rather looks like transients at source.

Over and out..,  I hope.
