It is also true that I have poor reception: all the BBC* channels seems to work okay - about 18 channels - but none of the non-BBC stations. Also they are not there on a 2nd scan, so I guess they are weaker.

UK is a little bit special case as it uses different channel raster. I 
just looked and there seems to be "auto-With167kHzOffsets" which could 
be used. It scans all the possible channels using auto parameter detection.

> So obviously there are a lot of rough edges. I also think it is a bit stupid for w_scan not to offer writing *all* the formats, since all the information should be there after a scan. It takes about 8 minutes to do a full scan. It would be more logical to generate all the channels.conf formats on one scan, and let the user throw away the ones he does not need, if it takes that long to do a full scan.

Yes there is. There is no many desktop applications supporting DVB and 
even less applications having own channels scanner.
