Have you checked what transmitters you get a signal from ? Plug your 
postcode (or better still, and accurate grid ref) in Wolfbane's 
checker :

There are many reports (particularly from areas near the edge of a 
region*) of people getting the "wrong" channels - eg BBC1 Wales 
rather than BBC Midlands (or whatever) with the "right" channel being 
shoved up to 800+ where standard Freeview kit tends to stuff 
duplicates.

I've personally had this (but not across regions) when tuning a 
friend's TVs where they pick up a weak (unusable) signal from a local 
infill Tx, but because this uses low frequencies these unusable 
channels fill in the normal numbers (1,2 3, and so on) and result in 
shuffling the proper BBC1 to 800 etc. In that case, the trick is to 
unplug the aerial cable until the scan has gone past the local 
frequencies.


For Myth, I'd suggest you look at your list of transports and delete 
all but the ones you want from your main Tx. Then instead of doing a 
full scan, do a "scan existing transports".
